Hi,
I built a system based on extensive advice from Aeacus over a year ago, namely https://forums.tomshardware.com/threads/new-build-questions.3836713/

System Specs
MSI ACE mobo
RYZEN 7950X3D CPU
RTX 4060 GPU
Corsair DDR5 RAM
Enthoo Pro case
Prime TX-1600 PSU
Dark Rock Pro 5 cooler
Noctua A14 fans

everything has been fine till now, but a recurring problem has emerged.

I have been doing a lot of backups of mainly 2T magnetic drives, and also verifying the copies are correct, over several days.
some backups can take more than 12 hours. so the machine has been under heavier use than normal for many days.

as I am trying to migrate my storage from USB2 enclosed sata magnetic drives to USB3 drives, mostly magnetic but a few SSDs, eg 5T magnetic USB3 ones, and 4T SSDs, and some 2T and 1T SSDs.

whilst one of some 490gigabytes was verifying, I went for a walk, and returned to find the PC had powered down. the lights on the Corsair ram was on. But I couldnt wake up the machine. Eventually I tried to power it off with the power switch at the top of the the Enthoo and nothing happened. so I powered it off at the mains.

now what happens is sometimes it will boot like now, but at some point there is a click from the machine and the power goes, but the Corsair rainbow lights continue. Other times the power cuts out before it reaches the boot options. It is quite frustrating.

I tried powering off all the USB hubs, as I have three USB3 hubs with 10 ports each, ie 30 USB3 sockets via hubs and more than 20 are in use, but at any time I might just use maybe 4 of those. the others are connected up but are powered off. I have the Sabrent 10 hubs. Items are powered off at the mains switch if mains powered, or at the hub socket switch if powered by the hub. The idea being to minimise attaching and detaching as that wears out the contacts and the hub becomes junk.

and also detached the sata cables to 2 magnetic drives in the tower in case any of these was the cause of the problem. but the problem persists, I can power up sometimes like now, but at some point there is a click from inside the machine and the power goes, but the Corsair memory modules rainbow lights continue. And the power button at the top of the machine doesnt work to power off fully.

I cant determine where the click is coming from.
 
that review says the Seasonic is ATX3.0 up to 1000W, but not for higher power up to the 1600W

If you look at the dates, review of TX-1600 was published in 2022, while TX-1600 ATX 3.0 was released in 2024. And the latest, TX-1600 ATX 3.1 was released Q1 2025.
Specs of the latest: https://seasonic.com/atx3-prime-tx/

No reviews of the TX-1600 ATX 3.1 as of yet.

There is even a special edition of TX-1600, named Noctua Edition,
specs: https://seasonic.com/product/prime-tx-1600-noctua-edition/

It is much quieter in operation than regular TX-1600.

Aris'es review: https://hwbusters.com/psus/seasonic-prime-noctua-tx-1600-atx-v3-1-psu-review/

So, if all what you need is quiet operation, TX-1600 Noctua Edition would be the best option for you.
At the time when i constructed your build, more than a year ago, that PSU wasn't released yet. It was released Q3 2024.

looks like the Corsair AX1600i outdoes the seasonic on many things, BUT the Seasonic is twice as quiet!
Well, Corsair AX1600i is made by Flextronics (one of the best PSU OEMs). In fact, AX1600i is the ONLY consumer model from Flextronics, which otherwise only produces server PSUs.
Moreover, AX1600i is one of the very few fully-digital PSUs, a true marvel of PSU's engineering. :sol: But AX1600i is now getting old, initially released in 2018.

Though, Flextronics will not be making any other consumer PSU as of now. So, the one PSU they did make, in collaboration with Corsair, is and most likely remains, as sole consumer PSU from Flextronics. Which is sad, considering how well made the Flextronics PSU is and what features it has.
It would be prime time where all PSUs should be fully-digital (with the features fully-digital PSU brings, like software monitoring and control, nigh-perfect efficiency) but alas, PSUs are still analog. There are some semi-digital PSUs but most PSUs are still "dumb" ones.

I have to be careful then to not buy the ATX3.0 one!
ATX 3.0 or 3.1 is actually better (modern) than old ATX 2.5.

I have now read all 4 reviews, looks like the Corsair RM1000x is also good in its own way, apparently the fan only starts at about 400W, so for my usage where the power is maybe 188W it is totally silent.

The Seasonic is less than 6dB up to almost 700W, according to the cybenetics review if you search in the page for "NOISE GRAPH".

sometimes a firm will do something just once, which is particularly good, and they never do any more.

I find this with Lidl, where they will sell something really superb, and then never again!


It would be prime time where all PSUs should be fully-digital (with the features fully-digital PSU brings, like software monitoring and control, nigh-perfect efficiency) but alas, PSUs are still analog. There are some semi-digital PSUs but most PSUs are still "dumb" ones.
analogue can have its own advantages,

with hifi, some top end systems just had volume control and balance, no bass and treble, no graphic equaliser, their argument was that perfection cannot be improved, so if the system is top level, bass + treble + graphic equaliser can only add distortion.

with electric guitars, where I taught myself just to a very basic level, I went to a store with a large basement of electric guitars and amps, and asked for a demo of the different equipment, basically amplifier and guitar. the guy took a high end guitar, and connected it to one amp, and played a bit of music, sounded great. then he connected it to another amp, and it was like listening to a rock legend, it was sublime, like the best guitar music I have ever heard, and this is in a shop! where it left the other one sounding like junk.

I asked the guy, "how come this one is so much better than the other one?",
and he said: this one is a valve amp, the other one is solid state ie transistors.

he said buskers prefer the solid state ones as they can be used with a few AA batteries, but the valve amp can only be used from the mains, and it needs time to warm up and is much more expensive. But the sound is like on another level. so dont underestimate the old fashioned analogue technology! I plan to buy a valve amp eventually, but too many other things to do before that!

analogue doesnt have any bias to specific frequencies, the response curve will be smooth, its only bias is that the curve is not a straight line and there will be trouble at the low end and the high end. human hearing isnt digital but is spectral, where there is a sensor for each frequency for maybe 15000 frequencies, whereas vision is kind of digital, where there are sensors for 3 frequencies red, green, blue, and other colours are interpolated eg yellow = red + green. thus analogue music is much nicer to listen to as it responds to all nearby frequencies identically where you get better frequency separation than digital. digital responds to say F, F/2, F/4, F/8, F/16 ... for some fixed frequency F, thus frequencies which are slightly different get interpolated which isnt as good. F, F/2, F/4, F/8, etc will be correctly done, but all other frequencies will be interpolated as a combination of F, F/2, F/4, F/8, F/16 so technically arent proper sine waves. Human hearing being spectral means there is a lot of overlap which is why hearing is such a rich experience, its like having 15000 primary colours for vision instead of 3. whereas 16 bit digital sound kind of has 16 primary frequencies, when our ears can do 15000!

cassette tape is only some 4mm wide, and is 2 sides of 2 tracks, ie only about 1mm per track, and CrO2 cassettes are quite impressive. think now what say 1cm of tape width per track would be like! and very easy technology to engineer. they never made this because of the problem of piracy.

Whatever frequency is used as the base frequency for digitising sound, it can never be aligned nicely for all 15000 sensors, but with analogue music technology it is. They dont sell analogue music equipment any more, so people dont know what it was like, its because it was so good that people became obsessed by it.

industry has gone for digital technology, partly because it is easier to engineer, as the engineering can be done as software, but analogue technology can be far more advanced, eg a mirror is analogue, and eg holograms. But it is very difficult to work as it requires analogue mathematics, ie calculus.

with say hard drives, magnetic drives are kind of semi analogue, and they are still cheaper and larger capacity than SSDs, eg you can get a 16TB magnetic drive for £181. SSDs are faster and quiet. But the thing is a magnetic drive is dumb technology, its just some material, whereas an SSD needs components for every binary digit!

Here's Cybenetics report of the TX-1600 Noctua Edition: https://www.cybenetics.com/evaluations/psus/2521/

Noctua Edition remains silent up to ~1100W output.

Also, at ~200W load, Noctua Edition is 92-94% efficient, while RM1000x at 200W load is 88.65% efficient. Meaning that Corsair PSU, at same 200W load, consumes more power and also wastes more electricity as excess heat.
92-94% efficiency = 80+ Titanium
88% efficiency = 80+ Bronze
Quite a stark difference.

sounds like ATX3.0 might be preferable to ATX3.1!
Well, there are two differences between the two;
* ATX 3.1 provides +12V-2x6 connector (improved connector over old 12VHPWR connector)
* ATX 3.1 standard specifies minimum hold-up time to be 12ms (ATX 3.0 and ATX 2.x had it at 17ms)

Relaxed hold-up time is an issue, but to know for sure if ATX 3.1 PSU actually has the lower, ~12ms hold up time, rather than higher ~17ms hold-up time, you need to either read the review or Cybenetics report.

For example TX-1600 Noctua Edition has hold-up time 24.1ms, which is far greater than 17ms and double of required 12ms.
RM1000x hold-up time wasn't tested in the two reviews i linked. I even looked up 3rd review and hold-up time wasn't tested in there either.


Oh, i made an error when i stated RM1000x 2015 warranty period. It isn't 10 years, but instead 7 years (written so in all reviews).
I just assumed that 2015 version also has 10 year warranty, just like 2021 version has it. But i was wrong.

So, when you bought your RM1000x in 2018, it's 7 year warranty is either up or will end soon. So, be wary of your RM1000x giving up the ghost any time soon (because this, 7 years, is what Corsair thinks the PSU would last without issues). Now, RM1000x is good quality PSU and should last longer, but at least, it's something to think about.

For analog vs digital, it needs to be looked case-by-case basis, rather than overall.

There are some products where the analog version is better than digital one.
E.g audiophiles swore by the vinyl records and vinyl players for proper audio, rather than the digitally made audio. Peripheral analog input (PS/2) is better due to no latency, compared to digital input (USB). Etc.

But then there are those where digital is better than analog.
One of them is video signal. Analog video signals (VGA, DVI-A) are limited by the resolution and refresh rate, whereby those can not produce e.g 4K 120Hz image. For displays, digital (DP, HDMI) is better due to higher bandwidth. Digital PSUs can achieve 99% efficiency, while analog PSUs peak at 96%. Etc.

I guess that means indirect noise by causing the tower fans to start sooner

it would be crazy if Seasonic reduced that just to conform to the standard!

what you want is max(ATX3.0, ATX3.1), ie on each specification whichever is the better of the 2, then they can say:

ATX3.0 AND ATX3.1 compatible, unless there is a conflict between the 2 standards.

For example TX-1600 Noctua Edition has hold-up time 24.1ms, which is far greater than 17ms and double of required 12ms.

I havent used it too long, probably some months with my earlier PC, and now whilst the Seasonic is returned. I bought it when Maplins went bankrupt, as you had to buy then or never. I got it at a good price, I think it was something like £45, and then it was in storage till probably early 2024. thus hopefully it will last say 6 years without fault. once it gets a fault then its better to buy a new one.

yes, the video is much better as digital. I think also because vision is kind of digital, a digital technology works better. the retina cells are kind of pixels, and they are either on or off, higher intensity causes more frequent nerve signals.

for audio, you need to buy old era equipment to decide for yourself, if you listen on high end equipment eg in a listening room, where these are arranged like a nice home lounge, the sound is sublime! they wouldnt arrange listening rooms if they werent! eg in this era those listening rooms have vanished, because the technology isnt good enough for a listening room!

with vinyl, some records are better made than others, the higher quality vinyl is thicker, where it is both flatter and also there is more leeway for the groove. The quality ones are heavier also. Cheap manufactures were very thin. Today's redone ones seem to be high quality.

the hifi equipment for the general public was generally rubbish, where CDs sounded better, but if you got top end equipment it was vastly better than CDs. Things like turntable decks are very difficult to engineer properly, so the cheap ones were rubbish.

basically average CD players are much better than the main record players, but the higher end turntables vastly better than CDs. I cannot listen to CDs for more than an hour as the sound aggravates my ears. but with analogue, I could listen for hours.

I got a german manufactured Dual CS505-mark 2 deluxe turntable, which was award winning, lower end of top end. Outright top end was seriously expensive. my deck had an independent suspension for the turntable and was indirect belt drive, whereas say my brother had a sony. with the Sony if you walked around the upstairs room, the deck would boom with resonance as you walked round the room, as the deck didnt have independent suspension. whereas the Dual wouldnt get that resonance, as the independent suspension was a shock absorber. so the german deck was much better engineered.

indirect belt drive is also better as it gives some leeway if there is any obstruction.

the Sony had very clear sound, but wasnt so good for bass. whereas the Dual was all round good. The arm of the Dual had a counterweight, which you rotated to get it perfectly balanced, then you applied a small bias on the gauge, to get optimal pressure. whereas a cheap deck doesnt have that level of perfection. The official diamond needle is by a danish firm called Ortofon who still make the needle.

the Dual also didnt use a strobe to get the speed accurate, instead it just used room light, because in those days the room light was 50Hz, so that was sufficient to get the speed accurate. today's lights dont work, but I kept some old era filament bulbs for tuning it!

I think the needle had an elliptical cross section, so you could orientate it 2 ways, the one way produces a "wetter" sound.

the loudspeakers I got were manufactured by a shop in house, large items 52cm x 26cm x 26cm, with bass and treble, and an air vent so the air can escape for bass! higher end speakers could have bass, treble and midrange also.

when I connect it all up, the sound is magic!

the cassette deck is by Teac, and does CrO2 and metal tape, and also Dolby B and Dolby C, where CrO2 + dolby C is as good as vinyl.

the cassette decks they sell today usually are just for iron oxide cassettes which are the lowest quality, and they dont do Dolby C.

metal tape was the highest quality, but was too expensive, usually more expensive than a vinyl album.

whenever I say about my system, people then say about Technics turntables. but in the hifi era, japanese components were generally only good for cassette decks. their turntables werent that good. the top turntables were either german or scandinavian.

it was generally regarded that indirect drive was better than direct drive, I think all the japanese things are direct drive. on the internet technics try to say direct drive is better, but it isnt. With hifi a basic blunder is confusing the specification with the actual experience.

if you visit the Dual site, you will see their turntables are still belt driven, the germans are the top analogue engineers in the world,

Dual turntable of today

the hifi afficionados of the analogue era would tell you without hesitation that belt drives are best.

my mum had a direct drive japanese vehicle and my dad had an indirect drive french one, and the french one was 10x better experience. the direct drive vehicle was very jumpy! whereas the french one totally smooth experience.

and it was just a matter of observation that the Sony direct drive had a major resonance problem. If you look at say cars, german cars vastly better than japanese.


Japanese items would always say how good their stuff is, but in a listening test they werent as good for turntables, loudspeakers, amps.

the best cassettes I found to be japanese, namely Sony. Didnt like the TDK ones. Philips ones were rubbish.

each cassette brand has a different sound, eg different Sony CrO2 tapes had different sounds. generally also best to get 60 minute, not 90 minute, because 90 minute is 50% longer, they use thinner tape which is more likely to get tangled!

british manufacture was good for amplifiers and loudspeakers, but not for turntables.

for hifi, the general idea was that your ears are the final judge, a product can use some technology and rave about this, but when you listen its a different story!

where with PSUs you can make conclusions on numerical data, it doesnt work like that for hifi!

the amount of things I listened to that had superb specifications but were rubbish sound!

Standard is at least 12/17ms. More is always better (preferred actually).

E.g my Seasonic PSU [SSR-650TD] hold-up time is a mythical 35.5ms. :sol:

Cybenetics report: https://www.cybenetics.com/evaluations/psus/1811/

This is due to the reason that many people care little, if any, about PSU's build quality. Instead, all they look is price and max output wattage, without considering if the PSU itself even meets the, very relaxed, ATX PSU standard or not. And more often than not, folks running those cheap PSUs come out of the woodwork once the PSU goes belly up and fries something else as well. Many good MoBos and GPUs have died due to the person being a cheapskate and they cheaped out on a PSU.

One of the latest example is this topic: https://forums.tomshardware.com/threads/blue-screen-event-41-bugcode-59.3878675/

I see people cheaping out on PSUs often in TH forums. But what annoys me most, is those blokes who can easily afford 500+ $/£/€ GPU and have no problem forking out that much money for a GPU (or CPU) but become very stingy when they need to fork out 150-200 $/£/€ for proper PSU.

There are some things that i like the old analog/manual way, rather than the new digital/automatic.
One such thing is using ignition key to turn on the car's engine on/off. Rather than the start/stop button many modern cars have. Because that button is huge security risk. Thieves can copy the key fob signal, reproduce, open the car and start, because car thinks the right key is near it. But with physical key and ignition switch, the digital signal can't be copied because car won't turn on if there is no manual/physical turning of the ignition switch.

But i do like some digital/automatic features as well. E.g i like automatic transmission over manual transmission. While i know how to drive with both, automatic transmission is far more convenient, especially when driving in city. Manual transmission is more work and while it can be fun, i'm too old to burn the rubber of car tires.

Oh, another, so called analog/manual thing that i like, is gasoline/diesel powered cars, compared to "digital" fully electric cars. I just find way too many flaws with electric cars that i don't like.

Sound wise, i know very little about hi-fi and can't comment on that. But this much i can say, that i prefer listening digital audio. Especially since my favorite music gerne is Trance (Epic and Classic Trance to be precise). Even now, when typing this, i'm listening Epic Trance channel from DI.FM. :) And that, via my headset, which produces "digital" 7.1 surround sound.

All-in-all, i think best is when you have a choice between analog/manual or digital/automatic. So, you can choose the one that suits you the best. Not having a choice is a poor option, since you may not like what it offers and you may prefer the other instead.

Many good MoBos and GPUs have died due to the person being a cheapskate and they cheaped out on a PSU.
in my case, I tended to just buy from what was available at shops such as Maplins, as I thought all that mattered was the wattage being higher than the sum of the wattages of my equipment. so its a case of ignorance. I wasnt even aware that PSUs have fans.

I follow the german principle of total perfektion, where I max the quality of everything, unless the price is way too much, or there are conflicting phenomena, eg I dont want noise and heat, so I dont necessarily want top end if it as noisy as the engine room of a ship, or if the room gets too hot.

by doing this, if I upgrade one component, the other components can probably handle it. whereas if I buy cheapest possible, literally everything else then has to be upgraded, or you get mystery crashes from insufficient total power.

now when I got the electric guitar, I got cheapest possible guitar, which cost something like £60, and got a Roland Cube Street amp, which is a standard busker amp. Here the rationale was I knew nothing at all about electric guitars, so I want to buy cheapest possible to then learn from direct experience what to go for. From doing that, eventually I will buy a quality guitar for maybe £600, and a valve amp. It was a good decision to start cheap, because I learnt some subtleties, where had I bought expensive it would have bought the wrong expensive guitar!

I see people cheaping out on PSUs often in TH forums. But what annoys me most, is those blokes who can easily afford 500+ $/£/€ GPU and have no problem forking out that much money for a GPU (or CPU) but become very stingy when they need to fork out 150-200 $/£/€ for proper PSU.
in Britain, people often will pay the absolute minimum they can get away with. it is maybe a hangover from the 1800s, when people had no money and no belongings, where the attitudes carry on.


There are some things that i like the old analog/manual way, rather than the new digital/automatic.
One such thing is using ignition key to turn on the car's engine on/off. Rather than the start/stop button many modern cars have. Because that button is huge security risk. Thieves can copy the key fob signal, reproduce, open the car and start, because car thinks the right key is near it. But with physical key and ignition switch, the digital signal can't be copied because car won't turn on if there is no manual/physical turning of the ignition switch.
yes, it sounds like a flawed system. I generally like to do things old school, its because I grew up in the 1970s and 1980s, where I only saw calculators and digital watches for the first time when I was 11.


But i do like some digital/automatic features as well. E.g i like automatic transmission over manual transmission. While i know how to drive with both, automatic transmission is far more convenient, especially when driving in city. Manual transmission is more work and while it can be fun, i'm too old to burn the rubber of car tires.
I got my first car 2016, so I only know the automatic transmission. what I like is the old school brake and steering wheel and gears, but with automatic transmission where it simulates the old era, but without the effort.

I really dont like press button brakes, also I dont like eco cut out. if I get in a traffic jam, I just switch the engine off, I dont need a computer to make the decision for me!

I like the manual gears as I find them therapeutic, I hope I never have to use a driverless car.

also I always switch off autocorrect with computers and smartphones. I like to know how to spell words, I know the few words that I cannot spell and sometimes will mis-spell them, but I know I might have made an error.

Oh, another, so called analog/manual thing that i like, is gasoline/diesel powered cars, compared to "digital" fully electric cars. I just find way too many flaws with electric cars that i don't like.

my current car is diesel, what I like is I can refuel for more than 600 miles in a few minutes!

and it is quite cheap, my last refuelling for mainly city driving, ie mostly 40mph, but also 30mph and 20mph, was 16.5 pence per mile.

when I eventually upgrade, I may get a hybrid car, that way I can continue using fuel, but also conform to the clean air zones. petrol cars currently do conform.



Sound wise, i know very little about hi-fi and can't comment on that. But this much i can say, that i prefer listening digital audio. Especially since my favorite music gerne is Trance (Epic and Classic Trance to be precise). Even now, when typing this, i'm listening Epic Trance channel from DI.FM. :) And that, via my headset, which produces "digital" 7.1 surround sound.

All-in-all, i think best is when you have a choice between analog/manual or digital/automatic. So, you can choose the one that suits you the best. Not having a choice is a poor option, since you may not like what it offers and you may prefer the other instead.

the thing is trance music is created digitally, so it is kind of tautological that it is best listened to on a digital system.

the music you are into is what I call mood or theme music, where it creates a mood or theme and can be quite lengthy as it creates an ambience. The earliest theme music I heard was oxygene by Jean Michelle Jarre, which I first heard around 1978, the URL says its from 1976. I dont know what you think of that, this of course is majorly off topic!

there is a saying "you cant miss what you dont know", so if you havent experienced quality pre electronic music on a quality analogue system, you wont be aware what you are missing.

electronic music on analogue systems is good! eg in the 1980s, there was all kinds of digital music on vinyl, eg OMD did some really interesting songs, and you have songs such as Vienna by Ultravox, which has a lot of synth. the synthesizer music began appearing everywhere around 1980. Although Giorgio Moroder was dabbling with it even in 1975 eg the Donna summer hits, such as this one. in the 1970s the music generally was old school, where they used imagination to create interesting effects. A japanese guy called Tomita did a very interesting rendition of Debussy called snowflakes are dancing

if you wanted to try that, for a turntable you cant go wrong with a Dual, you'd have to research what they have, but the sound of my 1985 Dual is superb. You also need an analogue amplifier, probably get a second hand one, and old era loudspeakers.

here is a brochure by Dual from around 1985 on the predecessor of the one I have, namely the Dual CS 505 mark 1

the engineering is very extensive, eg where the stylus applies very subtle pressure on the groove so it is not overpressed.

so its a bit like the high end PSUs, where they optimise everything.

the belt drive means the motor is separated from the disk, so you dont get vibrations transmitting through, and also it has a bit of slack. There is a gap between the central plinth and the outer frame, where it has its own suspension which thus aborbs shocks eg from people walking around in a room with floorboards.

from Google ": Direct drive tables pack a punch with higher torque, while belt drives are more the slow and steady wins the race type. Noise & Vibration: Direct drives have made leaps and bounds in reducing motor noise, but belt drives with their rubber belts have that natural edge in reducing vibrations and noise."

if you have heard both in action, you wont go near a direct drive turntable with a bargepole!

So, now, your PC is working fine with RM1000x?
Also, as you said, you're currently taking a break, before buying 1000W UPS.

If there are any more questions in regards of your PC (or UPS), ask away. :) Until then, topic can be suspended.
Oh, we can do casual chat within PMs.

yes, and I have messaged cyberpower as to which of their UPSes are silent, no reply yet, I'll post here if they reply. I suggested also about a thermostat controlled fan and to put decibels at 1m ratings.

I also messaged Eaton as to whether those UPSes are pure sine wave, also no reply yet. I suggested to them also to put pure sine wave and decibels in their filter.

the UPS has been received by the seller, no refund yet, and I havent heard anything further from Seasonic via the other seller as regards the warranty claim, just that they have forwarded the PSU to Seasonic.

I got the ESD bag samples, and its much better to have those to make a decision, I opted for 2 specific sizes. Main problem is the lengths rather than the widths. their largest size is ginormous, I think 24" x 30" where you could maybe fit 2 mobos!

the USB silicon covers also arrived today.

one thing which hasnt arrived yet is the UPS to UK power cables.

ok, a little bit of progress, I have the refund on the 2200 and also the refund on the 3rd party warranty.

I finally got some info on the Cyberpowers, the guy says all the pure sine wave ones make noise eg when the battery sets in, and I am getting clarification as to whether they are silent when no power cut and battery fully charged.

could you test the 2 you have if they make noise when you disconnect the power to force them to battery?

also could you run down the battery of one, and then test if it makes a noise when charging.

and say test what distance for the sound to either vanish or be barely audible, I know that will vary from person to person depending on how good your hearing is. Maybe if you go to a silent environ for an hour or two before you test this, so your hearing is more responsive, eg say first thing in the day.

I dont mind noise when on battery or when charging, as we usually only get momentary outages in Bristol, full enduring power cuts I think maybe 1 or 2 per decade. thus virtually never will I be on the battery power, but it is there to shield the equipment and enable continuity for brief outages, and orderly shutdown for enduring outages.

charging up will only be when the item first arrives, which is a one off, and beyond that when there is an enduring power cut, which is a few times per decade so not a problem. what is a problem is when the noise is incessant and perpetual.

he said if you found your CP1300 "quieter" then I should expect that for the CP1600.

he says the only fanless ones Cyberpower do are the OR series (Office rackmount),
but that these are simulated sinewave.

my guess and hope are that your one has a fan, but it only activates during battery usage and maybe also battery charging.
 
could you test the 2 you have if they make noise when you disconnect the power to force them to battery?
Well, once the main power fails, there is loud click of the relay and alarm will start blaring off. At that time, whatever small fan "swoosh" there is, it isn't audible.

also could you run down the battery of one, and then test if it makes a noise when charging.
I don't quite have a good load to put on the UPS, to run it's battery down. My PC, at max load (CPU and GPU bench), peaks around ~200W, and it would take ~30 mins before UPS gives out. But i'm not going to risk power failure when CPU and GPU are benching. Else-ways, i'm looking at data corruption or the worst, CPU and GPU failure. And i'm not going to risk that.

On top of that, i live in an apartment building and i can't have the alarm blaring off from 30mins. We have neighbors around us. That, and we also have a doggo, who has very sensitive hearing.

what is a problem is when the noise is incessant and perpetual.

he said if you found your CP1300 "quieter" then I should expect that for the CP1600.
I've said it twice now, that my UPSes, both of them, are dead silent during normal operation. Meaning when UPS isn't in battery mode.

So, you would be fine with CP1600 as well, since it is essentially the same series as my UPS is (except CP1600 is newer).

my guess and hope are that your one has a fan, but it only activates during battery usage and maybe also battery charging.
In these very rare instances, 2-3 times within the last 6 years, when power has gone out for longer than 1h, it has took us few mins to save our work and shut down our PCs, once UPS alarm starts blaring off. And at that time, we haven't heard any fan noise from the UPS.

We don't keep our hardware in sleep mode when we aren't home. Instead, we do full shut down. So, our UPSes have never used up all the battery power. And once the PC is shut down, i also turn off the UPS (since UPS being on also consumes a bit of power and would drain the battery). Once the main power returns, i turn both UPSes on, let them do their thing (e.g if they need charging) and then turn PCs back on, when we need to use our PCs.

the following manual CP1300 manual on p3, item 5. says:

5. Silence Alarm Switch
The toggle frequency is set to one time per 0.5 second. Press the switch to roll up the function
menu. Holding the switch for more than 2 seconds will silence the buzzer.


so does that mean you could silence the alarm for an experiment?

because if a UPS is used in an unmanned scenario, eg say someone in a university department, might set their PC to process some data, then return home, where they want the UPS to shield from danger, but they dont want the alarm resulting in police helicopters and commandos appearing at the building.

on the more recent models it looks like its the "Mute" switch, usually with electronics mute means to halt audio output, the verb means to silence something, and a person who cant talk is also called a mute.

if you run on battery for say 10 minutes, then that would also lead to recharging, without risking the hardware.
ie boot up, silence the buzzer, switch mains off, after 10 minutes power down the PC. Switch on the UPS, and see if it makes any noise. then reactivate the alarm.


On top of that, i live in an apartment building and i can't have the alarm blaring off from 30mins. We have neighbors around us. That, and we also have a doggo, who has very sensitive hearing.

can you temporarily silence as described above, and just run down the battery for say 10 minutes?

then no annoyance to the neighbours or doggo, and no risk to the PC.

when you are asleep then you need the alarm, but no need for the alarm if using the PC and say the lights are on, as you can directly see there is a power cut, thus I would imagine you can opt out of the alarm.


I've said it twice now, that my UPSes, both of them, are dead silent during normal operation. Meaning when UPS isn't in battery mode.
I believe you on that, I just wanted to understand the cyber power guy's insistence that they arent silent, and eg is battery charging non silent, and how loud? there are 3 separate forms of noise, when its charging, when it isnt charging which you say is silent, and when the battery is used.

he hasnt replied to my further query.

So, you would be fine with CP1600 as well, since it is essentially the same series as my UPS is (except CP1600 is newer).

but in that circumstance you wont be in the mood to see if the fan makes a noise!

sounds like a good idea, no need to have the UPS on if it isnt going to be utilised!

what I am wondering about is if the other firms you mentioned, whether the decibels they gave are when the battery is in use or if it is even when the battery is full and no powercut.
 
I dont mind noise when on battery or when charging
I've already confirmed that on normal operation, my UPS doesn't make airflow cooling noise. And since you stated that you don't mind the possible cooling noise when UPS is in battery more and/or charging battery, what you currently know, should suffice. Right?

Moreover, people hear sounds differently. E.g something that is quiet for me, may be annoying to you, due to the pitch or resonance of the audible noise. And that i can't even convey to you with recorded video (e.g using my smart phone to record a vid of my UPS), since sounds mutate in recording.

E.g the CP2200 that you returned. You said that the operation airflow noise was annoying to you. I think that for me, the small "swoosh", wouldn't be an issue at all. Since i have a high tolerance against small swooshes and i don't mind them. I don't need dead silence around me (heck, i even can't get dead silence if i wanted to, since i don't live alone and we have a doggo + neighbors all around).

ie boot up, silence the buzzer, switch mains off, after 10 minutes power down the PC. Switch on the UPS, and see if it makes any noise. then reactivate the alarm.
Switching the mains off is the difficult part for me, since our power sockets doesn't have switches. It then means i need to pull the UPS power plug from the Schuko socket. But the thing is, that socket is located behind our desks and it isn't easy to get to it. It means i have to unplug the PC, lift the tower part off the desk, remove other items from the desk, so that the desk gets lighter enough for me to pull the desk away from the wall, to get enough clearance to reach that said socket. And this is so for the both of our PCs.
Very tedious thing to do.

I do recall, that when i got both UPSes, i initially did recharge the batteries for 8h and at that time, there was no airflow noise i could hear.
The pics i shared in my reply, reply #59, 2nd pic under spoiler, shows the UPS being charged after unboxing.

what I am wondering about is if the other firms you mentioned, whether the decibels they gave are when the battery is in use or if it is even when the battery is full and no powercut.
You need to contact them all and ask them if you want to know for sure. But to me, i'd expect the noise constantly since it isn't stated that the noise is only during battery mode or during battery charging.

best assessment is a verbal assessment as to what you hear directly, sound recordings are always too different from the original.

a subjective description of how it is to you, how it compares to other things for you.

hifi in fact is about this problem, hifi isnt about music sounding nice, but is whether the recording sounds the same as the original sound, ie does the recording have "high fidelity": is it faithful to the original sound. similarly with printers you have colour profiles, to more accurately depict colour. both with hifi and colour profiles, the thing which isnt feasible to replicate is the volume of sound and the lighting, because even in a room, the lighting is a bit different at each point. live music will depend where you stand in the room, stereo is just how it sounded at 2 sample points.

your brain also rejigs the perception, eg a lower quality radio, initially you notice the low quality, but after a while you just hear the music. Now with a high quality system, you'll enjoy it more, as there will be better separation of sounds, and a wider frequency spectrum, low quality systems cannot handle 2 different sounds at the same time, where the sound is neither here nor there, ie a bit indistinct, and wont handle high and low frequencies, eg deeper bass sounds can vanish. with a quality system you'll hear the lyrics better, and the sound will be more subtle.

I junked some Sony headphones once as they had enhanced sound, where everything sounded nice, but the voices of famous people on the radio were totally incorrect. So nowadays I wont buy anything which says "enhanced".

my Samsung Ultra 24's audio playback will have high frequency sounds which I didnt hear in reality! so the frequency response curve for those frequencies is too high. Now this could be useful for say hearing what someone said! so its good for hearing everything that happened, but isnt high fidelity, as high fidelity should be a flat response curve, not one which whizzes upwards for high frequencies!


E.g the CP2200 that you returned. You said that the operation airflow noise was annoying to you. I think that for me, the small "swoosh", wouldn't be an issue at all. Since i have a high tolerance against small swooshes and i don't mind them. I don't need dead silence around me (heck, i even can't get dead silence if i wanted to, since i don't live alone and we have a doggo + neighbors all around).

as regards the neighbours it does depend on the technology of the walls, doors, floors. Here I can have the hifi on quite loud in one room, and you wont hear it from another room, this is because the housing development uses a nonstandard technology of 3 plasterboards per side of wall. where there are 6 plasterboards between any 2 neighbouring rooms, 3 on each side of the wall. non neighbouring rooms will have 12 plasterboards.

I once used an air pump, which is dangerously loud and from the other rooms you didnt hear much.

As a student I lived in one hostel, where if anyone anywhere on the 2 floors put some music on you could hear it in all the rooms.

Thus with this development, provided people are in different rooms with both doors shut you will usually get silence.

with a quality hotel, you wont hear the people in the other hotel rooms!

in Britain at least, a cheap wall will just be some bricks, the room will be a bit cold, the air not nice to breathe, and you'll have sound echos. You'll hear noises from the other side of the wall.

so usually outer walls have in fact 2 brick walls, an outer one often made of bricks, an inner one often made from much larger concrete blocks. the gap between the 2 will often have some kind of light insulating boards with a foil surface also to reflect back heat. and in this era the gap between the 2 walls will be filled with some insulating stuff where they fill it with a pipe of "stuff", called "cavity wall insulation", where the government created grants so people can have these done for free or cheaply.

now within the house, if that was it, the air would be cold, there would be echoes when you talk, the air wouldnt be nice to breathe could cause a headache. so a properly made place will have plasterboards attached to the wall, these often will be painted to seal out mould, and then you can have wallpaper, or even tiles. Thus the outer wall has a lot of layers of sound and heat insulation:
1. brick wall
2. insulation filler
3. heat reflecting foil
4. insulation slab
5. concrete block wall
6. plasterboard
7. paint
8. wallpaper

the outer wall might have further stuff, and could be painted. the more modern thing is to not paint as the paint WILL DETERIORATE, whereas bricks tend to not deteriorate with time.

the inner plasterboard 6. makes it easier to attach large paintings or wall cupboards. if you just had concrete bricks, it is more work to say attach a painting hook. plasterboard also softens sound so you dont get as much echoes.

internal walls between rooms, generally will have a wooden lattice for the underlying structure. they then have plasterboard on the outer 2 walls, and between these they may put fibre glass as further heat and sound insulation. these generally are made by carpenters, not bricklayers. I had 2 walls removed and new ones made at a different location, and took photos of the construction steps. the specific construction does depend on the specific carpenter's MO, and also the customer's requests. eg I requested the 2 new doors to be outward opening, as british houses by default have all doors inward opening, which is impractical. I also requested locks on all doors, that way if there are workers in the house I can control which rooms they have access to if I go shopping. As they will spy around otherwise!

now where they minimise the components of the internal walls, you can hear the people in the other rooms. similarly some shabbily constructed houses will have much less components of the outer walls, and you will get noise from outdoors.

the modern houses also usually have double glazed windows, which keep out external noises. I visited a house once near a larger rail station, and they had triple glazing! and there was total silence from outdoors!

they do still create some with single glazing. But the owner of the house can have those upgraded, usually can be done in one day.

anyway, a wall isnt just a slab of bricks, but there is a lot of technology and alternative MOs for walls, and I am just describing what I have seen, I am not an expert. when done properly eg in a quality hotel, you wont hear anything at all from the other rooms. one holiday we visited as tourists a monastery in south of France, and despite extremely hot weather, it was cool in the monastery, because of the use of rock walls.

fibre glass both for loft insulation, and between walls greatly reduces the amount of sound that comes through the ceiling or walls.

Switching the mains off is the difficult part for me, since our power sockets doesn't have switches. It then means i need to pull the UPS power plug from the Schuko socket. But the thing is, that socket is located behind our desks and it isn't easy to get to it. It means i have to unplug the PC, lift the tower part off the desk, remove other items from the desk, so that the desk gets lighter enough for me to pull the desk away from the wall, to get enough clearance to reach that said socket. And this is so for the both of our PCs.
Very tedious thing to do.
you have to move heaven and earth!

this is the advantage of wall socket power switches, that you can disconnect with less effort.

could you do it instead via the "fusebox"? where I am aware that these days they dont use fuses!

You need to contact them all and ask them if you want to know for sure. But to me, i'd expect the noise constantly since it isn't stated that the noise is only during battery mode or during battery charging.
I contacted Eaton about whether their ones are pure sine wave, and no reply several days later!

I used the cyber power contact forms, no reply. I phoned their UK number which was just a mobile number and got to ansaphone, and they never replied. One email to their UK technical support email address they did reply, but didnt reply to the further enquiry.

I think I'll put all this on Trust Pilot, that these firms customer support is worse than useless!

I havent yet contacted the other ones, as I hadnt thought of asking whether quiet when no powercut and battery fully charged.

where you say you expect constant noise since it isnt stated, the thing is these firms are highly uncommunicative, so it wouldnt surprise me if they just guessed some numbers!

its something where you need external reviewers like what you said about PSUs, who can measure the decibels at different distances, maybe even plot a frequency distribution of the sound.

because at the moment these firms arent forthcoming with information.

with hifi, many firms would just invent their specifications. this is why the hifi afficionados would only evaluate by directly listening. even frequency response curves arent much use as that doesnt deal with frequency separation. some equipment might be brilliant at handling sine curves. but if you send it a superposition of 2 sine curves, it might not be able to handle that as superpositions can have sharp changes at certain points which requires faster responding hardware. and eg they sometimes create hardware to smooth out sounds, where the hardware deliberately cant respond fast enough!

it is just incompetent design in this era of green energy to have a fan which is unconditionally on.

and its a good sign that your one is silent when fully charged and no power cut, whereas the 2200 by the same firm permanent fan on , which was like having a fridge in the room!

it wasnt just a swoosh like the Seasonic fan.
 
I've looked for many days now for a proper video review of the UPS and i finally managed to find the video of the very same 1500VA/1000W UPS you're thinking to buy.
Review video is nearly 1h long but he tests a lot. Also, it is recorded in Canada, so, they have 120V there. But otherwise, UPS is the same:

View: https://www.youtube.com/watch?v=TObKiyYOPds


I think this video can tell you much more than any testing i could do, since in the video, there is the VERY same 1000W UPS.

At 15:30, there is the part when he cuts the power and internal fan starts spinning. He even takes phone close to the fan for you to hear the airflow.

The walls in my apartment building are on the thin side. Well, walls are actually thicker than ceiling/floor is.

Just at today's morning, i was woken up by the neighbor above me, who's little daughter was crying/weeping and stomping their feet just above my bedroom. Mother scolded the daughter many times not to stomp their feet, which i heard clearly through the ceiling/floor, since all that stomping is amplified and is VERY annoying for me to hear (i already contacted the upper neighbor about stomping and now, they try to keep their kids not doing that).

But what amazed me, was when i was lying on the bed, in my quiet bedroom, i could clearly hear all the words mother was shouting to her daughter.

Since i have a doggo, i've asked my immediate neighbors if they can hear my dog bark and if that annoys them. My neighbors have said that they can hear the barks but since my doggo only barks few times a day and not constantly (not like another neighbor's dogs in our apartment building, barking all day long), my doggo barks doesn't annoy them at all.

The cross-section of the ceiling/floors here is such, from top to bottom:
1. Carpet. (above apartment)
2. Concrete slab with rebar inside it.
3. Ceiling paint. (below apartment)

Or when someone has made a better floor at their apartment, then it is like so:

1. Flooring tiles, e.g parquet. (above apartment)
2. Softening/leveling fabric. (above apartment)
3. Concrete slab with rebar inside it.
4. Ceiling paint. (below apartment)

We do not have dropped/suspended ceilings here.

Walls are essentially the same. E.g wall between my home office and my bedroom is (from left to right or vice-versa):
1. Wall paint.
2. Wall putty.
3. Cinder block wall.
4. Wall putty.
5. Wall paint.

Some may have wall paint, others may have wallpaper just on top of wall putty. Depends on individual taste. We have painted walls.

And wall between same floor apartments is a bit thicker. E.g, from left to right (or vice-versa):
1. Wall paint.
2. Wall putty.
3. Cinder block wall.
4. Ventilation shaft.
5. Cinder block wall.
6. Wall putty.
7. Wall paint.

All-in-all, the apartment building i live in, was constructed during Soviet time (construction started 1974, ended 1978) and back then, sound isolation wasn't a thought. Instead, constructing cheaply was a priority. So, essentially all Soviet era made apartment buildings have very poor sound isolation.

thanks for the link, I have now watched the full video. at some points the minutes indicator seems to move downwards a bit fast, have I misunderstood that?

do you really get the minutes it promises?

with these things, you should leave the plastic cover on the panel in case you need to return it!

luckily I kept that for the 2200, and was able to reinstate it before returning!

I think the resellers have extra boxes and things for restocking.

At 15:30, there is the part when he cuts the power and internal fan starts spinning. He even takes phone close to the fan for you to hear the airflow.

The walls in my apartment building are on the thin side. Well, walls are actually thicker than ceiling/floor is.
that will be why the noise problem, the one hostel I was in around 1991 was like that, if anyone anywhere talked or did anything, I couldnt study! in the end I did my main work at the department, where although I shared an office, I found some large unused offices in the basement which belonged to noone, and did my study there!


Just at today's morning, i was woken up by the neighbor above me, who's little daughter was crying/weeping and stomping their feet just above my bedroom. Mother scolded the daughter many times not to stomp their feet, which i heard clearly through the ceiling/floor, since all that stomping is amplified and is VERY annoying for me to hear (i already contacted the upper neighbor about stomping and now, they try to keep their kids not doing that).

But what amazed me, was when i was lying on the bed, in my quiet bedroom, i could clearly hear all the words mother was shouting to her daughter.
this is the problem I had in the hostel. The university people sometimes did things on the cheap for the accomodation.

if you have the right to modify things, plasterboard and things like fibreglass between plasterboard is the way to get soundproofing. for the ceiling also I think. when I had fibreglass insulation done for the loft, the place became a lot quieter, and also I didnt need the heater so much, as it insulated much better. Before that I had to put on the heating every 20 minutes in the winter.

if you dont have the right to modify things, you could potentially create a sound proof cubicle within the room. It would need some carpentry skills, or if it was me I would hire a carpenter. I give some photos of how both the internal walls and external walls are constructed here.

the original internal walls here have 3 plasterboards per side, and also they created storage cupboards between the 2 largest rooms (lounge and the larger bedroom of 2), so that means 12 plasterboards between this lounge and the main bedroom.



Since i have a doggo, i've asked my immediate neighbors if they can hear my dog bark and if that annoys them. My neighbors have said that they can hear the barks but since my doggo only barks few times a day and not constantly (not like another neighbor's dogs in our apartment building, barking all day long),

dogs are social animals, they cannot stand being alone, in the wild they go in a group. so if a person has a dog which they leave at home, the dog will bark and whine all day long till the owner returns!

I lived in a "studio flat" for a year after I completed uni, where a studio flat is a flat with bathroom, toilet, and 1 large room which is everything else, small kitchen zone and bedroom lounge. someone had a dog like that, which would bark and whine all day.

the way you fix that problem is you need to keep 2 dogs, then the dogs keep each other company.
with dogs such as dobermans, they actually take turns to keep watch. always one will be on guard, and the other might sleep, where they have a group psychology. if you see a group of dogs together, they get very happy.

dogs also dont like silence. Once at a station waiting room, there was a man with a dog, and it was making distressed sounds, then I noticed that any time anyone entered the waiting room it would calm down, but once the door shut it would continue distressed sounds. I figured it was it likes the sounds of the outside world, and doesnt like the silence of the room. so I put something to keep the door open, and the dog calmed down. so there are 2 compounding effects, leaving a dog alone, and also leaving it in a silent room eg no window open.

because you are there with the dog, it wont be in distress.

cats are different, male cats are solitary animals, whereas with say lions, the females go as a group as a pride of lions, with the cubs, once the male cubs become adult they leave the group. this prevents inbreeding. I think elephants also, the males become solitary.

my doggo barks doesn't annoy them at all.

The cross-section of the ceiling/floors here is such, from top to bottom:
1. Carpet. (above apartment)
2. Concrete slab with rebar inside it.
3. Ceiling paint. (below apartment)
the carpet would help insulate sound and heat. my place is ground level, and has a concrete floor, you then have say latexing which is very fine concrete to create a completely flat and smooth surface. they then put a further layer to waterproof that, and then tiles above that. I got bamboo tiles for one room, which are really great, twice as strong as oak and half the price. also no problem from woodworm as bamboo isnt wood but is a gigantic grass, grown in China!

upper floors in Britain can be floorboards, where they can have cables and pipes running under the floorboards. I dont know so much about floor structure, but I think ceilings in the UK have plasterboard. industrial buildings use a different MO, where they have steel girders and concrete, you have to observe ones under construction!

Or when someone has made a better floor at their apartment, then it is like so:

1. Flooring tiles, e.g parquet. (above apartment)
2. Softening/leveling fabric. (above apartment)
3. Concrete slab with rebar inside it.
4. Ceiling paint. (below apartment)
I think you need a plasterboard in addition to that, as that will soften sound, and improve heat and sound insulation.

direct concrete or bricks is unpleasant, and the hardness causes echos.

its bad for your health also to have direct concrete or bricks.

We do not have dropped/suspended ceilings here.

Walls are essentially the same. E.g wall between my home office and my bedroom is (from left to right or vice-versa):
1. Wall paint.
2. Wall putty.
3. Cinder block wall.
4. Wall putty.
5. Wall paint.

Some may have wall paint, others may have wallpaper just on top of wall putty. Depends on individual taste. We have painted walls.
if you put wallpaper that will improve things a bit, you can then paint the wallpaper.

not sure what you mean by wall putty, possibly you mean a plastered wall?

the plasterboards are a factory done version of that, where they have plaster attached to a board. then a cupboard will attach to the board part. its designed to carry quite heavy weights, eg a kitchen wall cupboard filled with plates and things.

And wall between same floor apartments is a bit thicker. E.g, from left to right (or vice-versa):
1. Wall paint.
2. Wall putty.
3. Cinder block wall.
4. Ventilation shaft.
5. Cinder block wall.
6. Wall putty.
7. Wall paint.

All-in-all, the apartment building i live in, was constructed during Soviet time (construction started 1974, ended 1978) and back then, sound isolation wasn't a thought. Instead, constructing cheaply was a priority. So, essentially all Soviet era made apartment buildings
have very poor sound isolation.

here in the UK, the government houses, which in fact are local government supplied houses, which are called "council houses" or "council flats", they have very good structure, but because they are free, the fittings are rubbish, eg they will have cheap vinyl floor tiles, really cheap rubbish kitchen cupboards etc. but the walls and foundation and ceilings will be top quality.

so its like having a top end tower case, top quality cables, top quality PSU, but everything else cheap rubbish!

Margaret Thatcher gave council house tenants the right to buy their council house or flat, and my place here originally was a council house, which the person bought, sold, someone else bought, and sold, and I am approx 5th owner! it was built originally in 1978. when I moved in, it was the original structures except someone had put a new carpet in one room, and replaced all windows with double glazed ones. The kitchen was the original rubbish.

the door was wooden, painted cheaply, mouldy surface! I eventually got that replaced by a luxury door.

2013 I renovated the kitchen, where it went from really bad to luxury. and 2017 I renovated the bathroom, photos of this next, which shows wall structure, both of external and internal walls.

the kitchen is 12' x 8', and the bathroom is just wide enough for a bathtub, plus a square along the long edge. so about 1.7m x (1.7m + bathtub_width).

photos of wall structure:

external wall structure
with this photo, I am having a wide short window removed, then the right side filled in with bricks, and the left side extended by the removal of bricks, enabling one to view the original structure.

lattice for a new internal wall

here an earlier wall was removed, and a new one is being built in a different position to make the bedroom on the other side of the lattice bigger, and the bathroom narrower. The new bathroom extends in the other direction more, so the total size in fact is the same as if it were rotated 90°. on the right they had to hack through the original structure when removing the earlier internal wall.

photo looking into the new bathroom zone

in this photo we have a new internal wall, with a doorway to the bathroom, and in the distance the original wall being reworked.

to the left of the doorway is plasterboards, which are screwed to the latticework. on the left of the doorway you will see 2 plasterboards. on the right is a cheap rubbish council house door! I had all those replaced by luxury ones at the end of the work!

a luxury door might just cost £60.

2 perspectives of the same internal wall

this shows on the left the latticework earlier on, and on the right the same walls where the plasterboards are now installed, where the RHS photo is from a different angle, and I have marked the same ventilation grille in the 2 photos.

photo within the bathroom of where the new sink will be

the construction of all this is very complex and coordinated, involving a plumber, an electrician, a carpenter, a bricklayer, a decorator,

in this photo higher up you see 3 parts of the lattice where the carpenter hasnt yet installed the plasterboards. I only photographed after hours, so the builders didnt know I was photographing. The carpenter will fill those zones with fibreglass before attaching the plasterboard. this new structure just has 1 plasterboard on each side, as I only learnt about the triple plasterboard per side months after the work was completed, from reading the manual for the original house. Otherwise I would have requested they do 3 per side! but they put the fibreglass between the 2 which insulates sound and heat. on this side is a bathroom, so not so much noise problem!

completed basin and oak cupboarding and vinyl floor

although the construction looks like a dog's breakfast, the end effect is luxury! the wall tiles are 75cm x 25cm ceramic ones from Turkey.

another view of completed basin side of bathroom

photo of almost completed bathroom

the basin and cupboarding was an ex display one which I got at a huge discount!

ceilings for newer houses are quite low, this one is about 233cm. that makes it cheaper and easier to do things, and cheaper heating. heat rises, so a high ceiling makes a room expensive to heat.

the original bathroom was really bad, and it jutted into the next room. if you imagine a 3.5m x 3.5m room, and then subtract out a bathtub zone, that was the next room! so I had the walls removed, and made that room fully 3.5m x 3.5m, and extended the bathroom into the wide corridor zone.

anyway, those photos will give you an idea of the british MO for internal and external walls, those external ones are from 1978. the UK does construction differently from all other countries, and it is continually evolving, with some very advanced ideas, and some ideas less good. eg in the UK we have natural gas mains, and most people use that for central heating. the US and Germany dont have this!

today's external walls have a bigger gap, and will have insulation boards with reflective foils, and the gap will be filled with much more insulating stuff than my ones.

if you want outright silence, you need to construct a cubicle within the room, with 6 successive plasterboards, and then also some stuff like fibreglass, fibreglass is quite unpleasant, so there might be some alternative.

constructing the bathroom is lots of components like for a PC, so I did a lot of researching for each, eg the bathtub is carronite, where this is very strong and insulating. the strength means it doesnt sag when you fill the tub, so the sealant doesnt separate. the insulation means the hot water remains hot. the previous bathtub I had to keep refilling with hot water every 15mins. the new bathtub I never have to refill, it remains hot!

in the UK, people who dont know how to build things are called "cowboy builders", as they stand a bit like cowboys!

if you get a building made by cowboy builders it will be really bad. To get everything done properly you have to go via an architect, who will subcontract to competent builders. and in fact it is the architect who ensures everything is done correctly. on youtube you should be able to find episodes of "cowboy builders with Dominic Littlewood", he challenges the cowboy builders who rip people off and do shoddy work. his slogan is "dont get done, get dom". its worth watching an episode, you'll see some really badly behaved unethical people!



 
thanks for the link, I have now watched the full video. at some points the minutes indicator seems to move downwards a bit fast, have I misunderstood that?
I didn't pay attention to the seconds counter on the video, since when i watch the video, i watch the content of the video, rather than seconds ticking down.

do you really get the minutes it promises?
Do note that the runtime is always estimation. So, depending on battery level and wear, same load may have a bit different runtime estimation. But thus far, to me, it has been accurate.

E.g my UPS, with my system currently at idle (me tying this reply), with 70W load, shows me between 42 mins, 46 mins and 51 mins runtime.
Then again, i haven't measured the exact time during power outage since, as i said, UPSes job is to keep the PC running when there is power outage, until you can save your work and safely shut down the PC. Not that you keep the PC running on battery power until UPS gives out.

if you have the right to modify things
Inside the apartment, we have right to modify all as we see fit. We can also tear down non-load bearing walls.

But we can not touch load bearing walls. Not even making a hole through it to other side. E.g making breakfast bar inside the load bearing wall.
37cd8bfdfd3ff52ba67005fe0e4af289.jpg

Direct link: https://i.pinimg.com/474x/37/cd/8b/37cd8bfdfd3ff52ba67005fe0e4af289.jpg

This is not allowed at all. Since it can jeopardize the structural integrity of entire building and make it collapse. So, no poking at load bearing walls.

For common wall plan, the bathroom and toilet are side-by-side, separated by non-load bearing wall. Nowadays, many people take the non-bearing wall out and make a one, big bathroom. Where shower/bath tub and toilet are in the same room. I, personally, don't like it since i can't use a toilet peacefully when someone else is taking a shower/bath.

not sure what you mean by wall putty, possibly you mean a plastered wall?
Basically, yes.

Wall putty is a white cement-based powder made of polymer and other minerals that make the wall look smoother. It is primarily used to fill in cracks and holes in walls and prepare an even wall surface before applying paint or wallpaper.

plasterboard and things like fibreglass between plasterboard is the way to get soundproofing
For soundproofing, we have modular soundproofing panels that can be attached to the concrete walls/ceilings. E.g Mute System 33,
further reading: https://www.jewson.co.uk/p/c-mute-33-soundproofing-for-ceilings-DIL01005

After which, plasterboard can be added on top of it. But it is expensive and i don't know anyone who has used it in their apartment. One ceiling module (1000x1200x33mm) costs €77 while one wall module (1000x1200x33mm) costs €69. While thicker module costs even more. E.g wall module (1000x1200x63mm) is €107.

the carpet would help insulate sound and heat.
Parquet floor is the norm here. Those who do like carpets (usually elderly people), have full carpet floors as well.
We have full/solid oak parquet floor, with some small carpets on top of it, for better grip for our doggo. Since smooth parquet floor is slippery for dogs and cats. While our bathroom and WC has tiled floor (since those are considered as "wet rooms").
 
I've looked for many days now for a proper video review of the UPS and i finally managed to find the video of the very same 1500VA/1000W UPS you're thinking to buy.
Review video is nearly 1h long but he tests a lot. Also, it is recorded in Canada, so, they have 120V there. But otherwise, UPS is the same:

View: https://www.youtube.com/watch?v=TObKiyYOPds

technical question for you as regards this specific UPS and UPSes in general, lets say the pure sine wave, line interactive topology ones,

say I have the 1000W UPS, and that I have the 1600W Seasonic again, with the PC's 1600W PSU connected to the 1000W UPS.

if there is no powercut, can I run the PC at 1600W?

I imagine I might only use 1600W for some graphics intensive things with a future graphics card eg I think it was the 4090 or something.

Now in that scenario, if running at 1600W is alright, then if there is a powercut, the UPS only supplies 1000W, what happens?

one scenario I imagine is the PC crashes,
but is there danger of damage to the graphics card or PC?

lets say any disk drive usage is read only. I dont know how much risk of damage to a hard drive for read ops when there is a power supply problem?

is it just for writes where there is risk?

as regards the walls, where there is total chaos for the bedroom on the other side of the wall in the earlier photos, and in those photos you will see a really rubbish carpet in that room. 4 years later during covid I finally had that room renovated. first problem was to empty the room, where to put all the stuff? and also just the effort as there was some heavy stuff. some photos:

photo of emptied room before renovation

with this photo you see deteriorated wallpaper, a totally rubbish carpet, dismal curtains, a dubious artex ceiling. that was the worst room in the place!

photo after walls, ceiling and curtains renovated

I hired some decorators to do the walls and ceiling, they sanded off the artex ceiling effect, they then plastered and skimmed it, then painted it, and reworked the walls, new wallpaper, then painting the wallpaper, storage cupboard door and ceiling. labour cost about £1000. curtains replaced by venetian blinds with colour matching the walls. the original rubbish carpet still in place. the room is about 3.5m x 3.5m. The wall on the left is the brand new one with brand new doorway and door of the earlier photos.

photo of room after renovation

here the floor now has also been renovated, with bamboo flooring, which is stronger than oak and half the price, flooring material cost some £500. you can strike the floor with a hammer and it wont affect it much. in the photo I moved some junk there temporarily. I have boxes of comics that I got talked into buying, where I want to sell off many and that is tricky.

that room is now the best room in the house! originally it was the worst.

for a place which has a noise problem, you can make that quiet via retrofitting stuff, this would be disruptive, but once the place is redone then much nicer. Best to go to an architect as they can coordinate the different specialists and they get trade rates, so it would be cheaper also. but you need to clad the existing walls with further plasterboard, with insulation filler between that and the original walls. the electrics need to be rerouted to the new surface. and then the new surfaces redecorated. thus it requires a carpenter, an electrician and a decorator. Now if I tried to do such myself that could take months. but the carpenter will do all that in a few days, the electrician probably in one day, the decorator a few days.

best to only renovate one room at a time, where you can make one room really soundproof. with some kind of cladding of floor, ceiling and walls. You have to ask around about cladding the floors as plasterboard wont withstand your weight. so needs another structure above it. but you need well trained tradesmen to do this kind of thing. they will do it matter of fact, like when I got them to move 2 walls, remove a window, make it narrower and higher.

in Bristol there are firms who specialise in soundproofing, eg for rooms for musicians to practise in.

with the 2nd photo, the electric sockets were redone, as I got the original 2 sockets replaced by 4, where the guy redid everything new. Went for the cheapest option of setting the wall sockets beyond the wall. The original ones were set into the wall. They can be done set in, but it is more work as they have to cut into the wall more, and as there is a radiator nearby it doesnt add much.

He also installed a further 4 light sockets on the ceiling, to get 5 sockets, as I like a lot of light in the winter. Later on I hired a carpenter to rehinge the storage cupboard door on the left! using the same door from the other side, needs some other modifications as well! with the 3rd photo it is now rehinged but not visible in the photo!

I think in the soviet era they deliberately made places so you could hear people, as they wanted people to be informants. where some of the neighbours would be informants.

there is a great drama about soviet East Germany versus West Berlin, called "the same sky", the title being that people in East and West Berlin would look up and see the same sky. Since the 1970s I have often explored the forests around where the US listening station in the drama is, which is an artificial mountain called Teufelsberg, created from all the buildings bombed in WW2. The americans used it to spy on East Germany.
 
I didn't pay attention to the seconds counter on the video, since when i watch the video, i watch the content of the video, rather than seconds ticking down.
the counter was losing a minute every few seconds!

Do note that the runtime is always estimation. So, depending on battery level and wear, same load may have a bit different runtime estimation. But thus far, to me, it has been accurate.

E.g my UPS, with my system currently at idle (me tying this reply), with 70W load, shows me between 42 mins, 46 mins and 51 mins runtime.

Inside the apartment, we have right to modify all as we see fit. We can also tear down non-load bearing walls.
ok that's good. You can definitely sound proof the place, just do one room, and carefully think which room to do. a smaller room will be cheaper, quicker and easier to do, where you can test out the idea.

the correct MO for such things, is to go to either a chartered surveyor to assess the plan, this might cost you £400 in the UK, where he will tell you what you can do including what you request, the costs, timelines, etc. Then you can decide whether to go ahead, and also modify the plan according to the costs.

Chartered surveyors can cost and assess anything from shelving a cupboard to building an airport!

the costs for such works are often based on the floor area of the room. so best to select a smaller room which you can repurpose.

But we can not touch load bearing walls. Not even making a hole through it to other side. E.g making breakfast bar inside the load bearing wall.
37cd8bfdfd3ff52ba67005fe0e4af289.jpg

Direct link: https://i.pinimg.com/474x/37/cd/8b/37cd8bfdfd3ff52ba67005fe0e4af289.jpg

This is not allowed at all. Since it can jeopardize the structural integrity of entire building and make it collapse. So, no poking at load bearing walls.
this is a reasonable prohibition. Changes to loadbearing walls require more expensive experts and more advanced construction skills, probably more specialised firms. they have to put a lintel if you create the breakfast bar in a load bearing wall. so you need civil engineers, and not the normal builders. Really should only be done via an architect, and valued by a chartered surveyor. Do not ask a builder to do such!

whereas nonload bearing walls can be reworked just by a carpenter. But its best to go via an architect, see later.

in the UK the loadbearing walls will usually have plasterboard cladding, where you could potentially rework the plasterboard level of it, but to avoid user mistakes they probably ban all reworking. with my kitchen the outer wall doesnt have plasterboard, whereas the bedrooms do. Trying to attach a hook for a net curtain in the kitchen is tricky!

For common wall plan, the bathroom and toilet are side-by-side, separated by non-load bearing wall.

Nowadays, many people take the non-bearing wall out and make a one, big bathroom. Where shower/bath tub and toilet are in the same room. I, personally, don't like it since i can't use a toilet peacefully when someone else is taking a shower/bath.
yes, better to have separate WC from bathroom. I decided no point in a large bathroom, where I extended the bedroom instead, I kept the bathroom the same size. I didnt think of the idea of separating the 2, so the 2 here are the same room. I managed to preserve the bathroom size, by changing it from 223cm x 170cm to 170cm x 223cm by making the corridor hall smaller!

Basically, yes.

Wall putty is a white cement-based powder made of polymer and other minerals that make the wall look smoother. It is primarily used to fill in cracks and holes in walls and prepare an even wall surface before applying paint or wallpaper.
ok, that in the UK is called plastering. there are 2 MOs for plaster, either plasterboard which is done at the factory, and used to construct internal walls. eg the URL you gave says to finish their product with plasterboard.

but then plastering by a decorator where they wipe the stuff on the walls, and "skim" it to make the surface smooth, and eg to smooth over imperfections in the walls.

with the new non bathroom walls, both MOs were used. the carpenter put the plasterboards. then a guy applied further plaster and skimmed this which conceals the screws attaching the plasterboard to the latticework. and the decorator wallpapered and painted the wallpaper.

the decorator also plastered and skimmed the ceiling for the bedroom renovation.

For soundproofing, we have modular soundproofing panels that can be attached to the concrete walls/ceilings. E.g Mute System 33,
further reading: https://www.jewson.co.uk/p/c-mute-33-soundproofing-for-ceilings-DIL01005

After which, plasterboard can be added on top of it. But it is expensive and i don't know anyone who has used it in their apartment. One ceiling module (1000x1200x33mm) costs €77 while one wall module (1000x1200x33mm) costs €69. While thicker module costs even more. E.g wall module (1000x1200x63mm) is €107.

they havent used it because 99.9999% of people arent thinking so far! its like most people dont get a quality PSU, because they dont realise that most PSUs are low quality. they just think a PSU is a PSU.

with this stuff, you are getting into a jungle. It may be best to consult a chartered surveyor or architect on this. do your own research, and then ask questions based on the research. with these experts, best to ask all your questions at the outset. put the questions in writing. Ask that you have researched different soundproofing panels eg the ones you mention, and ask about the options without those, to do it old school.

you then ask the expert for an upfront price for the valuation. He will then need to do a site survey. As he has to see for himself with expert eyes, what the circumstance is.

thus you need to be as specific as possible eg to do this specific room, what are the options, can he evaluate the Mute system 33, and also just using plasterboard and filler material. how viable is 3 plasterboards, what other options are there?

with these kinds of experts, you put all your questions at the start. Also ask for an up front price for the evaluation, and not to pay by the hour. that way you know what the advice will cost.

I got a chartered surveyor to value some work, and the guy said his fees are £95/hour, but that is open ended, so I asked if he could give an upfront all inclusive price, and he said some £400. He gave an extensive costed report, including removal of rubbish, removal of existing structures which he called "demolition", certification costs, labour costs, material costs etc.

the guy had a masters degree in engineering!


the guy will do a site survey, to measure things, to look at the existing structures, and evaluate things, and then will give you a report on the things you asked at the start. Make sure to ask for the timeline also for such works. An architect is better for further questions. As they are trained to deal with the general public, you need to go to a one man firm. the big firms deal with commercial projects.

potentially you could do your own experiments, create a small cube with say 3 layers of plasterboard. put a noisy item in it. shut the cube, can you hear the noise. you can then create multiple cubes of different materials.

as regards costs, go for the best soundproofing, and dont worry about factor of 2 in costs!
this stuff is a long term decision, and better to delay some months to save up for a more expensive one if it is significantly better. I have been using that bathroom renovation for 8 years, and the really good decisions are eg the heat insulating bath, non corroding towel radiator, huge mirror, extractor fan, cupboard. I have been using the kitchen renovation for 13 years, and it is still in brand new condition from using quality materials.

also if you get the work done by an architect, he will arrange builders who are proficient and prolific, where they will get trade prices, which will be cheaper than retail prices. in fact the architect will probably cost you entirely by area of the room, where the top quality ones will cost the same as the low end ones! as the professionals just absorb prices into the overall cost.

you will mostly not communicate with the builders, just with the architect, who then talks to the builder, who arranges the specialists, eg this work will mostly be carpentry. but you need rewiring of wall sockets and light switches.

so eg if you ask the carpenter a question, he will say you have to ask the building contractor. if you ask the contractor, he will say you need to ask the architect. if you ask the architect he will answer your question. your contract is with the architect, not any of the other people.


eg if you get a house extension with flooring, double glazed windows, radiators, electrics, this will cost the same as the house extension without flooring, double glazed windows, radiators, electrics! An architect told me in 2013 that extensions are priced by square metre regardless what is done. but only the things requested at the start. if you request stuff later on, then they invoice huge amounts, as this is "variation of contract".

so go for functional luxury, in writing, think it over for days if not weeks, research, then ask the expert.

thus get a costing for the max quality, as it will probably cost the same once you go to the professional firms. for the load bearing walls, ask about some form of movable cladding which doesnt modify the wall.

there are firms who specialise in soundproofing also, now I might go to an architect first for a costing, before going to a soundproofing firm, because in theory architects can do anything at all! so they probably know how to arrange soundproofing, which could be cheaper than the specialist firms.

industry will go to a chartered surveyor first, as their job is valuing and costing, and they keep spreadsheets of all costing works.

Parquet floor is the norm here. Those who do like carpets (usually elderly people), have full carpet floors as well.
We have full/solid oak parquet floor, with some small carpets on top of it, for better grip for our doggo. Since smooth parquet floor is slippery for dogs and cats. While our bathroom and WC has tiled floor (since those are considered as "wet rooms").

for bathrooms and kitchens, in fact linos can be best, they are the cheapest, and you can mop them with lots of water. tiled floors, eg mine are high quality vinyl tiles, water can get in between the tiles. now the surface under that is waterproofed.

for soundproofing from the floor below, you might need a more specialised maybe bespoke arrangement, of some kind of elevated floor with soundproofing under the elevation.

I would advise against trying to do these things yourself, although you'd save thousands of pounds, there are subtle problems you get.

eg when people install their own wood based floors, the floors often curve in the middle! this is because they havent put an expansion gap! The trained expert is trained in what goes wrong and the mitigations, so their work works perfectly first time.

eg I had the right hand side of the bathroom cupboard converted to shelving with glass doors by a city & guilds certified carpenter. and he arranged it so when you open the door the rotating hinge misses another surface by a few mm. where he had to arrange the cutting of the glass for the hinge etc, so he had to get it right first time. as an amateur everything will go wrong, and it will cost much more.

eg for kitchen cupboarding, the boss of the firm told me the most important thing of all is that everything is plumb, level and square. the reason is that if you then modify it, everything will be correct. we then did need to modify it, and the cupboard on the left and right were perfectly aligned. an amateur wont even think of these things!

I am definitely not an expert, where I know stuff this is from direct experience, either with works I have had done myself, or which I have seen done.

 
if there is no powercut, can I run the PC at 1600W?
I'd say: No.
Since UPS detects the wattage the PSU pulls and if it is more than the UPS is rated for, UPS would shut down, cutting the power to the PSU.

Same with PSU as well. If PC components combined would use more than 1600W, which PSU can not deliver, PSU will kill the power to the rest of the components.

one scenario I imagine is the PC crashes,
but is there danger of damage to the graphics card or PC?
There is always a danger of damage for sudden power loss.

Data corruption is most common. But hardware failure isn't unheard of either.

Hence why to get the UPS in the 1st place, so when there is blackout, power to the PC isn't killed on an instant. Instead, you can save your work (so no unsaved data is lost) and initiate proper shut down procedure.

For GPUs and MoBos, sudden power loss can cause firmware (BIOS) corruption and damage to power delivery components.

For HDDs, proper shut down procedure includes parking the write/read head at resting position, not leaving the arm in the middle of the platter which may cause head crash (where read arm touches the platter when it isn't supposed to, physically damaging the read/write head and/or platter).

For PSU, sudden power loss can damage the PSU, either by completely killing it or damaging it, whereby PSU isn't capable of operating as intended. Just like it happened with your Seasonic unit.

I imagine I might only use 1600W for some graphics intensive things with a future graphics card eg I think it was the 4090 or something.
Current king is RTX 5090, which is 575W GPU,

the counter was losing a minute every few seconds!
You mean UPS runtime estimation?

Official specs say that 1000W UPS with 400W load has runtime of 13.4 mins with full (100%) battery.
In the video, the battery wasn't full (87%) and initial estimation for 400W load was 15 mins, which dropped to 14 mins and then to 11 mins. That's expected.

It may be best to consult a chartered surveyor or architect on this.
We don't have chartered surveyors here. Also, architect here is only for drawing up building plans and projects and that's all.

Now, for e.g full renovation of the apartment, most of the times, the owner itself is the one who communicates between different builders, essentially acting as a foreman. But you can hire foreman as well, who does all that for you.

Best way for full renovation here, is to 1st contact interior designer, who helps owner to decide, select materials and envision what owner wants their home to be. While ensuring that everything fits within the budget.
For home renovation, we don't need to use architects, since those are used for bigger projects. Interior designer can also draw up floor plans. Once owner has the project completed, then owner needs builders who make it so.

Owner can either act as a foreman themselves and communicate with all the builders their own (usually preferred due to cheaper cost), or hire the same interior designer who acts as a foreman and communicates with builders on the owner's behalf. Many owners prefer to do some of the construction/demolition work on their own (mostly due to cheaper cost).
With any renovation, owner can also hire supervisor who's sole job is to ensure that the builders follow the project, while keeping within budget and time frame. But hiring dedicated supervisors are rare here, since it's additional cost. Only those rich enough can afford that, especially when they don't have time to be on site at all times and when they think interior designer isn't enough to ensure quality.

Hiring interior designer is also rare here since that's additional cost. Instead, most people think they can make it on their own (due to cheaper cost) but with this, it is easy to fall into pitfalls, where budget is blown before all the work is completed. And end result may lack quality as well.

We are lucky with our apartment since previous owner did the full renovation 1 year before selling the apartment, whereby we moved into fully renovated apartment.
 
I'd say: No.

ok, in that case if I wanted to use higher power things, I would connect directly to the mains for those uses.

But I think probably I wont ever use a lot of power. I am not into 3D graphics, in say the early 1990s I was, because the hardware couldnt handle that, so it was an interesting challenge for programmers to mitigate the slow hardware. For the Amiga 500 computer, with 7MHz Motorola 68000, David Braben created an impressive 3D game called Virus, where what he did didnt seem possible on the 68000! He used a lot of programming tricks.

Main reason I dont like 3D is I prefer reality! that is 3D, atomic resolution, no hardware can ever equal it because all hardware is part of reality!

3D games etc are always contrived and unrealistic. eg they will program in rewards for a certain kind of action. but the real world isnt like that.

this would be a problem just for magnetic drives?

what problems if any for SSDs?

I do use magnetic drives, for 3 reasons:
bigger
cheaper
safer: when magnetic drives wear out, they seem to slow down first, where you can salvage the data before they completely stop functioning. but I had a SATA SSD which one day just stopped functioning completely, no chance to salvage. luckily I had made a sector clone of the drive to a file approx 2021 or 2022, and had made directory backups of the work directory in more recent years. I have reconstructed the 2021 drive from the file clone, but I havent yet collated that with the more recent directory backups. the eventual reconstruction if missing any files will be just one or two.

so my MO now is to use magnetic backups of all things, but I use SSDs as work disks, as silent, and also fast. But to backup to magnetic regularly, only need to backup the directories that are modified.


For PSU, sudden power loss can damage the PSU, either by completely killing it or damaging it, whereby PSU isn't capable of operating as intended. Just like it happened with your Seasonic unit.

more modern things can be more efficient.

I realised I was playing the main vid at 1.5 and 1.75x speed, then going to normal speed for the more interesting bits, so it might have been counting down faster because I was playing the vid faster!


We don't have chartered surveyors here. Also, architect here is only for drawing up building plans and projects and that's all.

Now, for e.g full renovation of the apartment, most of the times, the owner itself is the one who communicates between different builders, essentially acting as a foreman. But you can hire foreman as well, who does all that for you.

For home renovation, we don't need to use architects, since those are used for bigger projects. Interior designer can also draw up floor plans. Once owner has the project completed, then owner needs builders who make it so.

Owner can either act as a foreman themselves and communicate with all the builders their own (usually preferred due to cheaper cost), or hire the same interior designer who acts as a foreman and communicates with builders on the owner's behalf.
if you get say a foreman or interior designer who can arrange the builders, that can be a better system as the guy will ongoingly forward works to the same people, so he can arrange people much faster, and he will know which people do quality work.

whereas if you do this yourself, you have to learn from scratch the hardway which firms are totally useless! You will have to waste time locating different tradesmen for quotes, and then maybe the guy does inept work.

Now if you kept doing this, eg say you had to renovate many places, or you renovate one room after another, you'd gradually learn the tricks, of which firms are good at what etc. The thing is most people just have the one specific work that needs doing.

in the UK with architects, they will arrange the builders, and the same firm will do ongoing work for them. Also this is what is called "B2B" business, ie "business to business", where the customer is also a business. this is usually cheaper as they charge less because they get more work ongoingly.

when a business is the customer of another business, they get a much more favourable rate, this is why if you order from a large firm, they will use UPS or DHL where it isnt feasible for you to. eg I ordered a DVD from the US, and they used DHL, but if I used DHL for that, it wasnt viable. many couriers in fact offer business deals, where if you post things every month, you get a much better price. TNT subcontract from the UK Post office, where for mass mailings they do a much cheaper price, where they collect all the mailings each day.

When you go to a firm directly as a retail customer, it is a lot of work and effort for a firm to get a retail customer, so they charge higher fees.

the firms who are good will work for say an architect, and they wont do work directly, as they get plenty of work from the architect and dont need a shop office for the general public. Builders are generally not the best communicators, as their expertise is physical skills, not talk. So they often prefer someone else to find customers. with many tradesmen, their partner deals with the customers eg phone enquiries, email enquiries.


Many owners prefer to do some of the construction/demolition work on their own (mostly due to cheaper cost).

when I had the kitchen renovated, they brought in a guy whose entire work was kitchen demolition. He removed and disposed of everything in one day! After that, rest of the work totally different workers, namely electrician, cupboard installer, plumber.

if you have the skills to do such things then you will save a lot of money, as this kind of skilled or onerous labour is high paid.

both the kitchen installers and the bathroom installers were very efficient and synchronised. where different specialists would appear at just the right time, and do quality work very fast. They will do in 3 hours, what will take me 3 weeks to do!


With any renovation, owner can also hire supervisor who's sole job is to ensure that the builders follow the project, while keeping within budget and time frame. But hiring dedicated supervisors are rare here, since it's additional cost.

although it is additional cost, the supervisor could have his contacts who he knows do good work, and can get a discount, where the cost is the same for you or even cheaper.

basically a lot of builders will rip off the customer, but they wont rip off the supervisor or other middleman such as architect. so even though there is an extra person it is cheaper!

where the middle man can arrange better works faster and cheaper. Trying to save money often is a false economy.

the reason one uses a chartered surveyor in the UK, is they know the going rates for ALL works. so they will tell you what the work should cost. this will help you avoid being ripped off.

say you want a loft conversion, or an extension, you have no idea what the price ought to be. so a firm can invent a price, and they do invent prices. And you wont know you are being ripped off. but the chartered surveyors know the official prices of all works.


the firm who renovated the bathroom, tried to rip me off for the extra works, where we hadnt agreed a price. I got a chartered surveyor to value those extra works, which brought the total value of the works down by much more than the cost of the valuation. in the UK if prices arent given up front, by law a firm can only charge "reasonable amount", the amount they invoice has no legal meaning. But you do need to pay for the work done.

you have to give prices before a work, for it to have legal meaning. in a court dispute, the court will appoint a chartered surveyor to assess reasonable value. so by hiring a Royal Institute of Chartered Surveyors person, they will give much the same price as a court. This enabled me to not fear the case going to court, and the firm eventually settled out of court by a big discount much more than the cost of the surveyor.

Only those rich enough can afford that, especially when they don't have time to be on site at all times and when they think interior designer isn't enough to ensure quality.


Hiring interior designer is also rare here since that's additional cost. Instead, most people think they can make it on their own (due to cheaper cost) but with this, it is easy to fall into pitfalls, where budget is blown before all the work is completed. And end result may lack quality as well.
if its a one off work, eg the works I had done were one offs, you will make all kinds of blunders. also in Bristol it is quite difficult to find any kind of tradesman. almost impossible to get an electrician or carpenter to do any work. Also the few who will value the work, often will then vanish, as its either too difficult or not enough work for them!


We are lucky with our apartment since previous owner did the full renovation 1 year before selling the apartment, whereby we moved into fully renovated apartment.

that's the easier MO, to find a place which is already done nicely!

some will renovate in order to sell either at a higher price or faster. The only thing is when I moved here, I had no idea what are the important things. I learnt all that the hard way.

 
3D games etc are always contrived and unrealistic. eg they will program in rewards for a certain kind of action. but the real world isnt like that.
There are simulation games that mimic real world closely. And if you include virtual reality as well, the current 3D gaming can be nigh-indistinguishable to real world.

Here's a good example;
Is it bodycam video filmed in real life? Or is it game rendered on the PC?

what problems if any for SSDs?
Since SSD doesn't have any moving parts, only issue would be data and firmware corruption.

but I had a SATA SSD which one day just stopped functioning completely, no chance to salvage.
Very same thing can happen with HDDs as well.

Though, as for SSDs, they have finite amount of writes. But modern SSDs are designed to distribute writes evenly (wear leveling) to maximize their lifespan, which can be 10 years or more. Once all writes are used up, SSD will act as read-only media. You can still access the data on it, but you can't write any new data to it (akin to CD/DVD disc).

Overall, SSD is more durable than HDD because it doesn't have any moving parts. With this, SSD is more resilient to physical shocks, vibrations, and drops.
HDDs, write/read arm and platters can be more easily damaged by physical stress. And since those components also move, it will wear out in time.
Average HDD lifespan is 3-5 years.

are you suggesting the RTX5090 with my system would work within 1000W?

does it draw more power than the 4090?
A bit more. 600W at maximum with power spikes to 644W,
review: https://www.techpowerup.com/review/nvidia-geforce-rtx-5090-founders-edition/43.html

I realised I was playing the main vid at 1.5 and 1.75x speed, then going to normal speed for the more interesting bits
I watch videos at normal speed, while skipping when need be (i look the preview thumbnail on seek bar to know where to skip to). At 1.5 or 1.75 speed, the sound is distorted and it would be difficult to make sense what is said.

in the UK if prices arent given up front, by law a firm can only charge "reasonable amount", the amount they invoice has no legal meaning. But you do need to pay for the work done.
Here, it is vice-versa. All the costs (materials, labor etc) is calculated up-front by the construction company and they give you full quote beforehand, often listing out how much individual materials and work cost. And once you have that quote, you can decide if to take that quote or ask the quote from another firm. Sometimes, some companies want 50% upfront before starting the work, but usually, it is all payed at once, after the work is complete.

Usually, it is best to take 2-3 independent quotes from different companies, so you can evaluate the offerings and choose which one to settle with.
This way, there are no hidden costs in the work. Heck, hidden costs are actually against the law here.
 
There are simulation games that mimic real world closely. And if you include virtual reality as well, the current 3D gaming can be nigh-indistinguishable to real world.

I think that one they have probably fed into a computer a real place, a bit like with Google Earth street view, where you can look around and its as if for real. then the game is based within that inputted environ. Now as a programmer I dont know how the software does that, but they have developed the software where you can feed in views of a reality scenario eg some ruins, and the software assembles the 3D data.

but the thing is no matter how good a simulation is, it is NEVER reality!

very important life skill is to know reality versus unreality. eg art, cinema, vid games, music, these are unreality. enjoyable, but not for real. A lot of young people get trapped in unreality. as people grow older, many start to move into reality and will tell you the unreality is nonsense.

reality is fundamentally different, a vid game is like a fictional story, real life is never like that! with a game, there is always an author who decides what kind of things happen eg Charles Dickens stories. so its always fake at some level. with real life, things happen very gradually, eg discussing soundproofing or UPSes. often we do things not knowing where they will lead to, eg people choose different courses at school and uni. and in fact success of any form is generally about gradual progress, where it can take months or years. eg trying to lose weight or do well in education.

with reality there is no overall plot, just different developments, eg I bought a 3D camcorder, I have filmed different geographical settings. I have sent that PSU and am waiting for progress on that. you get pivotal moments, eg you get accepted for a course, or you get rejected for a job, or you move to new accomodation, or you buy a new computer or other equipment etc. eg they either return the Seasonic repaired or refuse to. totally different from video games, where there is some guy early 20s, with no life experience programming in what he thinks should happen!

eg often creating shoot em ups, but real wars dont work like that! man to man combat means you have failed in warfare! you have to defeat the enemy without risk to yourself, eg the siege of Stalingrad, or Gulf War I where the US planes were beyond the range of the iraqi defences. war is about stealth, ambush, deception, traps, spying, not about man to man combat! shoot em ups are totally unrealistic. future wars will involve drones and robots.

real world also there is a ton of stuff beyond whatever you do, whereas eg with the above video simulation, you couldnt say head to an airport, fly to Bristol, visit the zoo, then go to the cinema, and then swim in the river Avon and then watch some vids on Youtube and then order an SSD on amazon!

they could try feeding things in like with generative AI, but it will always be fake.

at the end of the day then, one has to do backups, and backups of the backups as nothing is safe!


would the total for my system be less than 1000W then?

eg with the Seasonic when doing lengthy backups, the entire house was using about 188W,

say with the GPU at full power usage, if I minimise disk drive activity to what is relevant to the game or other program.

I guess I could look at the power monitor for the house to see what that says.


I watch videos at normal speed, while skipping when need be (i look the preview thumbnail on seek bar to know where to skip to). At 1.5 or 1.75 speed, the sound is distorted and it would be difficult to make sense what is said.
Youtube has improved a lot for sound when sped up, even at 1.75x speed its now fine.

earlier technology eg on some DVD players, and Youtube say some years ago the sped up sound is dubious, but youtube have improved the technology. its a question of how sophisticated the interpolating is done,

if you just speed up verbatim an audio graph, then voices become higher frequency, where they sound like cartoons, but if you speed up 1.75x the above Youtube review of the 1000W UPS, you will see the voice is the same just faster. that must require some sophisticated maths to do. potentially they might split the sound into segments, and discard every other segment.

eg split it into 0.1 second segments, [0-0.1] [0.1-0.2][0.2-0.3][0.3-0.4] then when you double the speed, the sound becomes [0-0.1][0.2-0.3][0.4-0.5], voices would then sound the same, but that might sound a bit clipped, so they might interpolate near the boundary of these segments. whereas if you just did [0-0.4] at double speed, the voice would become much higher. eg cue and review with cassette players, the sound would become really high frequency.




Here, it is vice-versa. All the costs (materials, labor etc) is calculated up-front by the construction company and they give you full quote beforehand, often listing out how much individual materials and work cost. And once you have that quote, you can decide if to take that quote or ask the quote from another firm.
can be like that here, depends on the firm. some firms will give an extensive itemisation, others will just give a brief statement of what they will do, and should give a price.

I got such a price which I accepted, but I then requested extras eg to rehinge the doors to open outwards rather than inwards, some doors to rehinge on the other side, to have lots of light sockets and power sockets installed, etc. And they evaded giving a price, saying "we'll just add it to your bill".

then 6 months after the works were completed, they sent a huge invoice for the extras.

Sometimes, some companies want 50% upfront before starting the work, but usually, it is all payed at once, after the work is complete.
the deposit is for 2 reasons:

by paying any deposit, even £1 it means you have legally accepted the contract, and also if you pay via bank or credit card, they can do a credit check on you. if your credit rating is too low they can refuse to do the work. credit ratings measure whether you pay your bills on time and by the minimum amount demanded by the contract. so eg with a credit card, the bill might be £100, but the minimum payment might be £5 by 30th July, so as long as you pay £5 by 30th July your credit rating remains maximum. a building invoice will want the money in full unless you have a finance deal. you then have to pay in full by the timeline given, which might be 2 days, 2 weeks, 30 days, or other amount depending on different factors. some firms want immediate payment, of course nothing can be immediate! and bigger payments could take some days to clear and the bank may do fraud control on larger payments in case someone stole your card.

if you dont pay by that time, your credit rating will start to drop. so a builder can tell if a person doesnt pay their bills on time and refuse to do the work.

the firm has to do the work on their own money, they have to buy the materials, pay the wages of workers, and only get the money after the work. this problem is an example of cashflow, and a lot of startups go bankrupt soon because they dont understand cashflow!

with business to business deals, eg a cleaning firm cleaning some offices, they might only get their money 1 month after the invoice. so that means first 2 months no money, as they invoice at the end of the first month, and a further month to pay. so all the cleaning, wages, equipment, fuel, etc has to be done on the firm's own money. many such firms then go bankrupt as they run out of money to pay wages etc!

where a firm has to use its own money to do the work, this is called "working capital". many firms dont understand this, and ask for large deposits. They dont understand that when an invoice is paid, that isnt spending money, but that a large percent is working capital for their next work!

eg if you buy a hard drive for £100, that isnt 100 of spending money for the shop, but maybe 60 of that is to replace the stock with a new hard drive. But amateur businesspeople dont understand this, and they spend all the money they make!

so the 2nd reason for the deposit is towards the working capital.

Usually, it is best to take 2-3 independent quotes from different companies, so you can evaluate the offerings and choose which one to settle with.
I try to, the bigger the work, the more quotes I try to get. eg for the bathroom and kitchen I tried to get 5 quotes. But one problem is for some things it is tricky to even find one firm to quote!

eg when I had that room redecorated, I could only find one firm, and they wanted 1000 for the work. it is very strenuous work especially the ceiling, as they had to sand the ceiling, replaster it, skim the plaster, paint it. the higher up you use your hands the more strenuous it is! it was during covid also, so I decided to pay the 1000. the actual materials for the work probably less than 100!


This way, there are no hidden costs in the work. Heck, hidden costs are actually against the law here.
but you might need to know the law and how to enforce it!

a lot of things get done by bluff where the customer doesnt know their rights and doesnt know the law. eg invoices for things where the price wasnt stated before the work. legally you can do this, but legally the customer isnt obligated to pay the amount, but is obligated to pay "reasonable amount". worst case it goes to court, and the court appoints a chartered surveyor to assess reasonable amount. this is why its important in the UK to get a chartered survey for a work, because that tells you where you stand if the firm demands a big amount afterwards.

if something is against the law, it is difficult to enforce the law, as lawsuits have to be about amounts disputed, and if the amount disputed is below 10000, all you can do is get your money back, the other person cannot be arrested even though they broke the law!

thus some firms become confident and will break the law left right and centre as they know they cant lose anything.

 
would the total for my system be less than 1000W then?
Well, do the math.
A bit of calculation;
CPU - rated for 120W, but can draw up to 165W (with PBO and undervolt, source)
GPU - rated for 115W, but can spike up to 148W (source)
CPU cooler - 120mm fan 2.4W, 135mm fan 3.4W (source)
Fans - NF-A14 industrialPPC-2000 - 2.16W per 1 fan or 15.12W per 7 fans (source)
M.2 - Samsung 990 Pro 2TB - up to 5.4W (source)
Current total: 339.32W
So, when you now replace 148W GPU with 644W, that would bring it to 835.32W. But that is WITHOUT any HDDs.

Also, i don't know what other components you're planning to use. But i listed you the power draw of all your MoBo ports:
But single SATA power cable, that comes out of PSU and usually has 3-4x SATA power connectors, can withstand up to 54W. So, entire cable can do 54W, not individual connector. Since Seasonic PRIME TX-1600 has 5x SATA power cables (4x cables with 4x connectors, 1x cable with 2x connectors), and if you do plan utilize all SATA power cables, then you can look at ~250W for those combined.

As far as all other sockets your MoBo has, well... sigh... 😒
PCI-E slot can deliver up to 75W. Your MoBo has 3x PCI-E slots.
DDR5 RAM, individual DIMM can pull up to 3W. Your MoBo has 4x RAM slots.
M.2 drive can pull up to 12W. Your MoBo has 4x M.2 slots on board.
Fan header can pull up to 12W per header. Your MoBo has 8x fan headers.
USB 2.0 can pull up to 2.5W per port. Your MoBo has 8x USB 2.0 ports.
USB 5 Gbps can pull up to 4.5W per port. Your MoBo has 4x USB 5 Gbps ports.
USB 10 Gbps can pull up to 7.5W per port. Your MoBo has 10x USB 10 Gbps ports.
USB 20 Gbps can pull up to 100W per port. Your MoBo has 3x USB 20 Gbps ports. Now, back then, i looked in-depth into it and only one of the 20 Gbps ports can provide up to 60W, while other two are rated for 15W per port. So, total for the 3x ports would be 90W and not 300W.
Surely you can do the rest of the math by yourself, right?

I guess I could look at the power monitor for the house to see what that says.
Or do that.

but the thing is no matter how good a simulation is, it is NEVER reality!
This is only when you know for a fact, that you entered/exited from simulation. But if you do not know that? Then how can you differentiate what you see/experience, from the actual reality?

Prime example is when you sleep and see dreams. For you (your brain), whatever you see, is reality. Since your brain and in turn, you yourself, consider it to be reality. Only when you wake up from a dream, you realize that it was just a dream and not reality.
In dreams, whatever you do there, you do not consider laws of physics. Thus, in dream world, one can do all sorts of, otherwise impossible, things. Some people fly. Other people have superpowers etc.

But when you never wake up from a dream, there is no way for you to realize that you are in a dream. Instead, you still think you are in the real world and what you do, is all in reality.

There have been many movies about the dream world. One of the better ones is Inception (2010). And then there's of course The Matrix movie series.

What is there to say, that our current reality isn't a simulation, just as depicted in The Matrix movies? There are paradoxes (e.g Fermi paradox) and glitches (e.g cosmic glitch in gravity) in the real world, that, by the laws of physics, should not exist. But they do. Indicating that our real world is just a simulation. Very advanced simulated reality (simulation hypothesis).

3D simulation games mimic the real world. But virtual reality simulation games are getting pretty close to the reality. Only the fact that you knew that you entered/exited the virtual reality is the one that defines for you, that virtual reality isn't the true reality.

Also, there are video games out there, where there is a game inside a game.
From the top of my head: Breathedge. It is space survival simulation game. But in there, you can find an arcade machine, where you can play a game inside the game.

For a Type III civilization (Kardashev scale), it would be very easy to create realistic simulation inside the realistic simulation, which is inside realistic simulation. Maybe even Type II or Type I civilization is enough for such a feat. Considering that we are currently Type 0.7 or so and we already have near-reality simulations for people to experience.

Well, do the math.

So, when you now replace 148W GPU with 644W, that would bring it to 835.32W. But that is WITHOUT any HDDs.

Also, i don't know what other components you're planning to use. But i listed you the power draw of all your MoBo ports:

Surely you can do the rest of the math by yourself, right?

ok, I have taken a screenshot of the itemisation, so if I do use a higher power graphics card, I will study that and remove unnecessary items.

I actually only connect up sata drives as a one off, with magnetic ones I dont like the noise, so only connect them up to backup. I am kind of migrating everything away from the sata magnetic drives, to just use the smaller USB3 magnetic ones, off a powered hub.


Or do that.

could be easier for an overall calibration, as it would include the powered USB3 hubs if those are connected to the UPS.

then if the total power of the house is say getting to say 850W, to start removing unnecessaries via the itemisation, and eg to rearrange things to one powered hub.

This is only when you know for a fact, that you entered/exited from simulation. But if you do not know that? Then how can you differentiate what you see/experience, from the actual reality?

Prime example is when you sleep and see dreams. For you (your brain), whatever you see, is reality.
during the dream yes, although a few times over recent decades in a dream I realised it was a dream, with one such dream I then woke up but I woke up within the dream! still dreaming! apparently you can train yourself to detect its a dream within a dream, much like they do in the inception film, where the guy will spin a top.

now with dreams, when we wake up unless we write down the dreams within a few minutes, the dreams are completely forgotten. apparently its because the brain knows they arent for real so it junks them. you cannot trick your brain as to what is reality! this is why even with a dream, one doesnt remember the earlier dreaming much. if you write down the dream, then you will remember it.

its also why "paper trading" doesnt work. ie where you buy shares with pretend money. eg I'll put $10000 on Nvidia shares today, $5000 on Meta shares. where its just some numbers. when you trade for real its always different. the reason is your brain knows its for real, whereas paper trading it knows is not for real. so eg in movies, one often sees people with guns and one is unaffected. but one day in Bristol I saw some young men in the distance and one was brandishing a mere revolver. and I was horrified! its coz my brain knows the latter is for real, the former is fake. similarly in US movies one often sees cops, and not a big deal. but with my one visit to the US in the early 1990s, walking round the small city, there was a cop ahead, and I was astounded because it was like meeting Mickey Mouse. ie totally different because it was for real, all earlier cops entirely in films or tv programs. but because this one was for real, my brain reacted totally differently.

Since your brain and in turn, you yourself, consider it to be reality. Only when you wake up from a dream, you realize that it was just a dream and not reality.
but even in a dream, one forgets majorly, not so with reality. within the dream your brain knows its fake, and it wont record the memories. otherwise people would be really confused as 1/3 of their memories are dream memories. now there are a few places that I am not sure if these were dreams or for real!

also in a dream there is very limited free will, things just happen, there isnt much volition. One is mostly an onlooker in dreams.

during the dream you dont realise its a dream.

What is there to say, that our current reality isn't a simulation, just as depicted in The Matrix movies? There are paradoxes (e.g Fermi paradox)
the fermi paradox is easily debunked, it says from Google "it's reasonable to assume that life, and even intelligent life, could have arisen elsewhere"

yes, but it has to arise somewhere for the first time, and that could be us.

his assumption is NOT reasonable, that's the flaw, its not based on any logic or evidence. and overlooks the first timer for everything fact. eg the americans were the first country to land on the moon. Russia was the first in outer space, namely Yuri Gagarin.

also only humans have developed civilisation on this planet even after 3.22 billion years of land life. this makes it very likely we are the first ones in the universe.

scientists believe the universe is maybe 13.8 billion years old, land life is 3.22 billion years old, so there isnt a lot of time for other intelligent life to have evolved elsewhere in the universe. we may well be the first. the 2nd might be in 2 billion years, 500 million miles away!

perhaps elephants, whales, dolphins are more intelligent than humans, but they dont need civilisation. whale and elephant brains are kilos heavier than human ones! dolphin brains are similar size to human about 1.6kg. elephant brains have been recorded at 7.5kg, whale brains at 9.2kg according to my 1979 Guinness book of records.

so its like saying intelligent humans must invent writing, so people must have invented writing 100000 years ago. yes, but someone had to invent it the first time, which could be the civilisations of the last 6000 years such as sumer, indus and egypt.

the flaw with fermi is a very fundamental principle of logic, that for logic everything MUST have a starting point, and that applies to life. the only alternative is an eternal universe, and eternal life, but then we can bring in other alternative ideas such as destiny, where destiny prevents lifeforms meeting lifeforms which are at a different stage of development. same way humans keep kids away from university lectures, as the uni lectures are for a more advanced stage of development, and the kids would quit learning if they saw what awaited them years later at uni! Thus we keep people apart in different zones, kids at primary school, teenagers at secondary, young 20s at uni. its not fair to move them to the wrong zone.

ETs not visiting us here, is also easily explained: we are totally evolved for our specific conditions eg air pressure, gravity, when astronauts remain in space, their bodies start to deteriorate, and after a longer time in space, when they return they cant even walk. so even to settle on mars isnt viable, as the gravity is 38% of earth, after some months your kidneys in particular will fail. fluid builds up in the brain also. its like the PSU for a PC, needs to be very precisely delimited, you cant just plug any power supply into a PC! this planet is our PSU. Mars and the moon are the wrong specification!

if ETs arrive here, the conditions will be wrong for them, so they would either deteriorate or have to live in bubbles, not worth travelling 10 years for that!

and glitches (e.g cosmic glitch in gravity) in the real world, that, by the laws of physics, should not exist. But they do. Indicating that our real world is just a simulation. Very advanced simulated reality (simulation hypothesis).
could be, but its a much more advanced simulation than human made ones and there are philosophical problems eg where is this simulator? and what is the point of such a complicated arrangement? and if this world is fake, what is the fakeness based on? is it based on something real at another level? eg Warner Bros cartoons eg Bugs Bunny are fake, but they are based on the world the animator experiences. if its not based on anything else, then that seems a bit dubious.

we are existentially trapped in reality, whether or not it is a simulation, but we arent existentially trapped in a computer one. eg you cannot eat food in a computer simulation. it could maybe create the visuals, but it cannot supply you the nutrients of energy and minerals!

so at some point the fakeness will always surface. also you can just restart the game, but with reality you cannot restart, many decisions are irreversible. no second chance!


3D simulation games mimic the real world. But virtual reality simulation games are getting pretty close to the reality. Only the fact that you knew that you entered/exited the virtual reality is the one that defines for you, that virtual reality isn't the true reality.
they will ALWAYS be fake, there is only one reality, the one containing the computer with your simulation. such things are always programmed by young men with no life experience. when people grow older, they grow up and regard simulations as nonsense. these things only impress young men and Mark Zuckerberg, they dont impress women or older men.

no computer simulation can put food on your plate, or pay your bills!

in a power cut, after an hour of UPS battery support, your computer simulation will vanish!

whereas reality NEVER vanishes, it is always there, even when you sleep, even across a power cut, it has been there for 13.8 billion years!

one problem with the vid you gave, is video games are notorious for misleading representations, where the box will have these fantastic images, the intro vid will be fantastic, but the game itself very dismal! That vid states its a trailer, so falls in this category, and thus is inconclusive. when you actually play the game you'll be stuck in a very constrained subset, eg on the verranda, and only able to move 1m, then after a lot of gameplay you go through the door and now are there for a lot of gameplay! been there seen that so many times!

this is an old trick, like the gyms which have these photos of well built people. but the people using the gym are not, that's why they keep going there! some gyms will pay well built people to pose around outside the gym! discos and bars use this trick also where they hire really attractive women to loiter around unaccompanied. if a customer of the disco or club approaches them, the woman will use some put downs, where she is trained on this. if that doesnt work, they hire some men who then move in pretending to be the woman's boyfriend!

all these things are "bait".

Also, there are video games out there, where there is a game inside a game.
From the top of my head: Breathedge. It is space survival simulation game. But in there, you can find an arcade machine, where you can play a game inside the game.

the problem remains that each such thing has to be programmed in, so you can always push such simulations to breaking point. eg is there a mains supply to the arcade machine? can I obtain and attach a UPS to the mains? can I weigh the UPS? at some point the programming runs out. its the same problem of dishonesty, if someone is dishonest, and you keep interrogating them at some point they run out of road!

this is the problem with generative AI, that it is all programmed in. eg they found that when schoolkids got AI to write them a story, it was almost always about a girl called Elara who lived in the woods! its because that is all they programmed in.

even in 1989, people were trying to put realism in programs, but it would always be something very specific eg your arcade game, as each such thing has to be programmed in, and nobody can program in everything.

when you drive a car, bits of grit get caught in the tyre tread, will they simulate that?

if I hit the grit with a hammer, will it crumble?

I can keep pushing the simulation till eventually it will break. whereas reality will never break!

what is interesting about reality is it never runs out of stuff! and people will keep inventing new stuff. whereas with computer generations including AI, one is always trapped by whatever has been arranged by humans. the computer can be programmed to recombine that, but it is always ultimately trapped. Chatbots are based on words without meaning, but to truly understand something you have to go beyond words to the meanings. eg with soviet Russia, they would display Pravda in public places. but you always had to read between the lines. this is one of the differences between younger people eg under 25, and older people eg over 40, younger people are trapped in the words they have read and learnt. but the older person goes beyond words, and is sceptical of words. they trust instead experience, and will consider what is said but arent weighed down by this.

even a grain of salt is billions of atoms, you just can never simulate everything eg the ocean with bacteria, which have more than 700000 DNA bases in their DNA, just within one bacteria! you have no chance in hell to simulate even the bacteria in your mouth!

the computer will have to simulate itself, but that will be much slower than itself! so it is impossible for simulations to ever equal reality. if you narrow things down a lot, then a computer can be faster. but not if you keep throwing further aspects of reality, the computer will always run out of road eventually.

the guy who runs a TV station, he doesnt watch TV! because he knows its all nonsense.

For a Type III civilization (Kardashev scale), it would be very easy to create realistic simulation inside the realistic simulation, which is inside realistic simulation. Maybe even Type II or Type I civilization is enough for such a feat. Considering that we are currently Type 0.7 or so and we already have near-reality simulations for people to experience.

nonetheless, each level of simulation adds a big time overhead, ie will be much slower.

at a very basic level, a computer would have to simulate itself, and this will always be slower, the only way to get reasonable speed is with recursive hardware eg x86 does have recursive features. but nonetheless the simulation then has less memory as its sharing the same memory. so if you keep simulating within the simulation, eventually you run out of memory.

there is also the problem of disk drives, that the simulation needs a simulated disk drive, where the bigger this is, the less physical disk drive available for the simulator.

and in any case as soon as the recursive hardware simulates other hardware eg say x86 simulating ARM, then you get a big overhead of speed, where it will be significantly slower than the simulator. so eg today's x86 simulating the Motorola 68000 is vastly faster than an actual Motorola 68000. but the simulated Motorola nonetheless is slower than the simulating x86. so each such step eats something from the earlier level.

computer simulations generally are only simulations of the surface, they dont simulate what is below the surface. so eg in a shoot em up, the opponent doesnt have any kidneys, or a heart, or vertebrae! its just a surface simulation. if they simulated the internals it is vastly more computation and the simulation would be too slow and wouldnt improve the game!

 
So, when you now replace 148W GPU with 644W, that would bring it to 835.32W. But that is WITHOUT any HDDs.
I forgot to mention, I emailed the trader as to what progress on the Seasonic as almost 3 weeks now, and he said Seasonic now prefer to deal with warranties directly with customers, and not via sellers, but that he has forwarded it to them as a seller.

so in future with seasonic, best to do warranty claims directly with Seasonic.
