Suggest me an UPS for my pc

[3hunna]

I want to buy an UPS which can make my pc run without power at least for an hour cause the electricity in my country is bad it goes off after every 3 hours for an hour & I am sick of it & generators are a no go since they make a lot of noise & need fuel to run so I've decided to buy an UPS but I need help with the following things how much watts should the UPS be? how much VA & KVA & square wave or sine wave or pure sine wave & can someone explain to me what VA , KVA & what those voltage waveforms are??? what kind of battery will I need for it?


I've the following specs

4th gen i5
16gb ddr3 Corsair vengeance gaming ram
Seagate 1tb 7200rpm HDD
Corsair 240gb LE SSD
Gigabyte GTX 750 ti 2gb oc windforce 2x
Creative 7.1 sound card
Gigabyte H81 mobo
500watts Seasonic 80+ bronze certified psu
Corsair carbide 200R case with three Corsair 120mm AF fans + one Xigamatech 140mm fan

I've Creative 5.1 SBS A550 surround sound speakers & I am using a 23inch LG IPS 234v LED monitor on the power adapter of my monitor it says the following 19.5v
Input: 100-240v
50/60hz 125-160va
output: 19.5v 3.3A

I don't mind disconnecting my speakers when the UPS kicks in but suggest me an UPS that can at least run my pc and my monitor for an hour at least without no restarts


Homeage , Mercury , Emerson , Apc , Cyberpower , Alfa Digital are the following brands UPS the computer stores near my house are selling

Ok heres the problem. An hour is a LONG time, most UPSes last only about 15-20 minutes. So before I recommend one I wanted to get that out of the way. You can get one that lasts an hour, but you will likely spend as much as you did on your PC.

APC and Cyberpower are both good, I like Cyberpower because their prices are far more reasonable. an 800va UPS will give you about 450-550w of power maxed out depending on the model of UPS. To be honest your system won't draw nearly that nmuch so it would be more than enough for all your equipment.

The CyberPower CP850PFCLCD is 850va giving you plenty of power, its pure sine wave which if your psu is ActivePFC (probably is) helps prevent power loss when the battery is switching over.

Correct me if I am wrong but the only UPS that I've seen that last 15-30mins are low end ones I've even seen some that last 2 hours & the UPS that you suggested me will it run my net device too? cause a pc without net is pretty much useless & how many batteries can I connect with the Cyberpower UPS?? & tell me one thing if I want to run my pc for an hour will it depend on the UPS or on the batteries?? & what kind of battery will I need for it? I've heard from people that you should buy a battery which costs about the same as the UPS , Is it okay to buy an used UPS? & use a new battery with it or there are any cons like using an used storage drive can have bad sectors

2 hours on a fully running computer? You'd need a really expensive high end unit for that. I guarantee you have never seen one in a store that can last 2 hours.

I have this for example attached to my server:

https://www.tripplite.com/smartpro-120v-1kva-800w-line-interactive-sine-wave-ups-2u-rack-tower-snmp-card-option-lcd-usb-db9-6-outlets~SMART1000RM2U/

It puts out 800 watts and has a 15 minute run time at half load. Its also $500. So you can imagine what one that lasts an hour will cost, or 2 hours!

UPSes are batteries, its basically a giant surge protector and line conditioner with a battery in it. You don't need to buy anything additional or any other battery. The UPS I suggested you could definitely plug in your router as well so you maintain internet. But like I said 15-20 minutes tops out of it.

I would not buy a used UPS with a new battery. You don't know where it was and the surge suppression and line conditioning circuitry can wear down over time if theres a lot of outages or bad power in the area.

Well in my country there are China/local UPS too as well as branded ones don't know if the branded ones can do 2 hours but China/local UPS sure can I am getting confused you said ''UPSes are batteries'' where over here people buy an UPS device & connect an external battery with it & over here the UPS that can do 15-20mins cost about 50-60$ and good ones start from 80$ + but regardless of how much the UPS is you need to buy a separate battery for it over here for example if I buy a 100$ UPS I'll need to buy about a 100$ battery for it

but I was told by a friend not to go with local UPS as local ones are mostly used for fans and lights because they are square wave not for precision stuff like electronics and computers for precision stuff like computers, you'll need sine wave or a pure sine wave he said you can run a pc with square wave but the power supply's capacitors will degrade and damage the other components of the PC & he told me you might need around 50 AH battery to run it for 1 to 1.5 hours or so

 

[Rogue Leader]

Those UPSes you are talking about are not for computers, sure they will last 2 hours, but not powering what you want to power, they are junk compared to what I posted for you and the one I linked for my own.

Real life UPS devices UPS stands for Uninterruptible Power Supply, battery is practically in the name, how else would it be Uninterruptible.

A 50AH battery is like a car battery, those things alone are over $100. Then you would need a UPS to run it. Like I said something that can do that is going to cost you WELL over $500.

As I said in my first post you need to lower your expectations of what this will do, as well Computers are sensitive, if yo try to power it with a cheap device you will be sorry quickly.

So whats your suggestion to me should I just buy a laptop ? with discrete dedicated graphics & (get a wireless portable net device for it )as I've heard modern laptops can run on battery for 3 hours although I don't need one for 3 hours an 1 hour would be sufficient & if the laptop battery ever wears out they don't cost much so that shouldn't be an issue totally aware that laptops are inferior to a desktop in terms of performance & most of them are not upgrade-able with the exception of ram & HDD/SSD & that they heat up ( a laptop cooler would definitely help)

 

[Rogue Leader]

If the most important feature for you is something that lasts without power for at least an hour then get yourself a laptop, thats your only choice.

If you want the best performance and upgrade-ability, build a PC and get the UPS I suggested and you'll need to go without PC if the power goes out.

My confusion is cleared now UPS comes with an internal battery like you said yourself most will give you 15-20mins to save your important work after doing some research I found out how people be running a pc for an hour with an UPS what they do is they use an external car battery with an UPS so it lasts for hours instead of minutes ( depending on the battery/batteries) is there any cons to this? I mean using a pc with an UPS that's pure swine wave & certified for pc & you use an external car battery with it to make it run for an hour

[Rogue Leader]

That sounds like an easy way to blow up the UPS and burn your house down. I highly recommend against that.

 

[3hunna]

Hmm well the people in my country are doing that & none of the UPS blowed up even the square wave ones just like foreign tech recommend using anti static wrist band while touching the internal components of the pc & using compressed air cans to prevent static but over here no one wears that band or use compressed air cans people use electric blowers just like some people use window glass cleaner instead of LCD cleaner to clean their monitors & they never got damaged same as some people use unknown/non branded psus with their pcs & their pc never got damaged anyway I've decided to go with an Apc or Cyberpower UPS that can do at least 30mins ( I was able to find a few that stated 30mins) I'll try to get a pure swine wave or at least a simulated/modified sinewave with "line-interactive" so it can deal with voltage surges & get the external battery if the internal one doesn't make me happy you helped me somewhat , asking my friends on fb , doing some research on google & youtube I was able to get the answers to my questions the capacity of UPS is mentioned in VA( voltage amps) , not in Watts & KVA is another term for 'Watts'

As far as for damaging any components in my rig by the passage of time that won't be much of an issue as I constantly upgrade my components

So since no one else bothered replying & you're the only one that tried to help I'll select you as the best answer

 

[Rogue Leader]

If you aren't gaming on it you may be able to squeeze 30 minutes out of a "15 minute" UPS. Like if the computer is just idle or you're just web browsing. APC and Cyberpower (and Tripplite) are the best companies, Cyberpower is the cheapest especially for pure sine wave and as I said 800-850va is enough for your system.

 

[3hunna]

Hmm that's cool cause I don't need it for gaming I need it for chatting or downloading a game without interruptions by the way can you tell me whats the difference between an UPS & an Inverter , some UPS require software & some don't which one is better?

 

[Rogue Leader]

UPS will run without the software you don't need to use it, however the software offers diagnostics (you can see how long you have left on the battery) and things like automatic shutoff after a pre set time.

An inverter is not what you need, it converts DC current into AC current, so its how you would connect a computer to a car for example.

 

[3hunna]

After doing some more research not all UPS have internal batteries some do & some don't & that if I run my pc with a modified/simulated sine wave there's a chance that my pc would just restart cause my PSU is ActivePFC how ever I saw a comment in a different forum of a person saying if you run the UPS in narrow mode the restarts can be avoided I came to know its possible to get more time out of a small UPS by replacing its battery with a larger one but that depends upon the physical size of the UPS and its capacity to hold larger batteries & the second & the best option would be to buy an UPS that that has an external battery connector this is a safer, easier, and often more aesthetically pleasing option. The inbuilt charger in the UPS wont be able to charge a bigger battery anyway. Unless the UPS (Like some high end APC models) supports it, its NOT recommended. Buying a large battery with a separate charger for it which can charge large batteries and keep the charger with large battery always on this is the only way to run large battery with small ups.

 

[3hunna]

So currently the best option would be to buy an UPS that has an external battery connector option

 

[Rogue Leader]

There is no such thing as a UPS without a battery, it defeats the purpose of the name. And yes as I told you sine wave is what you need if you have an Active PFC psu. I have never heard of running a UPS in "narrow mode" and in fact such a mode does not exist on any UPS I have ever seen or owned (and I've owned quite a few).

APC does have models that you can plug an additional battery into, thats the only safe way to do this.

 

[3hunna]

Narrow mode this switch is also known as Voltage Range Switch & I visited a few shops today they had both Cyberpower UPS ones with internal batteries & ones without internal batteries the internal batteries Cyberpower UPS were all Pure sine wave & the ones without internal batteries were all modified/simulated sine wave the shop keeper told me you cannot use an external battery with an UPS that has an internal battery , I asked him if he has a Cyberpower UPS which is Pure sine wave & with which you can connect an external battery he said UPS like those exist but you won't find them in our city & will need to order one

I told my friend that he said the shop keeper is bull<LANGUAGE> cause you can mod the UPS with the internal battery to use the external one by opening the UPS saying you'll need to unscrew the bolt and attach the battery on the exposed connector and then rebolt ,

I am sure doing that will void the warranty & I am not a DIY guy ( I can get an electrician to do that)

but wouldn't it be better if I get an UPS that has an external battery connector option no need to open or cut anything can you suggest me any UPS like that?

 

[Rogue Leader]

The voltage range switch does change switchover time (for units that have it ) from a narrow to wide range (I guess thats what you mean by narrow mode) it basically changes the sensitivity of the UPS from around 110v to 170v. It does help with some sensitive electronics but I have never heard of it correcting the ActivePFC issue.

A UPS without a battery is not a UPS. I don't know what they showed you but the main basic function of a UPS is to provide backupo battery power. I poured over Cyberpower's entire site, they do not sell a UPS that does not have a battery, both sine wave and simulated sine wave.

Cyberpower does offer extended battery modules but only for their rack mount UPS systems.

APC offers them for some of their normal desktop UPS systems. SO for example if you buy this:

http://www.apc.com/shop/us/en/products/APC-Power-Saving-Back-UPS-Pro-1500/P-BR1500G

You can get this extended battery

http://www.apc.com/shop/us/en/products/APC-Back-UPS-Pro-External-Battery-Pack-for-1500VA-Back-UPS-Pro-models-/P-BR24BPG

And as we discussed modding a UPS with internal battery is a BAD idea, it seems you agree.

Also please watch the language.

^ I want you to take a look at this one

https://www.amazon.ca/Tripp-Lite-OMNIVS1500XL-Battery-Back-Up/dp/B0002935BA

 

[Rogue Leader]

I like tripplite as well, as I said I have one of their units. That one is good and has a nice extended battery option but the problem is its not pure sine wave so you may have problems.

You could always buy it and test it and if it doesn't work right return it. Its easy to test through the power alert software, or by just pulling the plug from the wall.

What about this one APC Smart-UPS SMT750 ? its pure sine wave & has the extended battery option too , So how much time do you think an extended battery can increase of the UPS? & does the extended battery has to be the same brand of the UPS?

Yes the extended connector is proprietary so you must use the same brand.

The extended battery will likely double the run time. Look at the chart on that page you can see how long they last at different loads. Like I said you can probably get a lot of time out of one if you're not gaming. But if you are even the biggest one will only last 30 minutes.

Also realize you will have spent $500 at this point.

Sorry I am late after I last replied here I shifted to my new house and didn't have a net connection here I applied to my ISP on Monday to install it here they installed it after 6 days I didn't buy the UPS yet cause of holidays the shops got closed so the UPS we were talking about can run my rig for 30mins right so what if I run a PS4 on it how long will the UPS run the Ps4 for? you'll probably say that depends on how big TV you're using with it I've a 42inch Ecostar LED tv on the specs it says it has IPS characteristics not sure what does that mean though I know what IPS is but to use less power I can hook the PS4 with my 23inch LG IPS LED monitor cause it has a HDMI port


& also if you don't mind can you help me out with my other problem I knows its not related to my post as I stated I shifted my house , I was using 8mbs DSL at my previous house I was getting 870kbs on downloads , watching movies in 720p online without any buffering but at my new house my net is browsing slow ( I know browsing depends on the DNS) my DNS is set to Google & videos are buffering even on 480p & speed.net is giving me 6.83mbs where as in my previous house I was getting 7.90mbs that's strange cause my new house is in a new area so it has new lines , the lineman installed a thick copper cable to the fiber optic distrubutor box and connected a small copper cable to the thick one by twisting them together & by the condition of those cables they looked like they were used/old so I had the lineman replace the old cable with a new one & he installed a TPI adapter box to connect the thick cable to the smaller one he said that should resolve your issue but that didn't make a difference

Do you think I am getting slow speed due to he didn't replace the smaller cable ( it had cuts and joints on it) ? or cause I am using the enternet cable that came with my box instead of using the expensive enternet cable that I was using before?

One of my friend suggested to call the ISP ( Internet service provider) & have them change your port ( can you explain to me what does that mean?

 

[Rogue Leader]

A PS4 will last a pretty long time on a UPS, the most it could ever draw is like 300 watts. If I had to guess I would think maybe 45 min to an hour. I could be wrong but Its possible (using a larger UPS like we discussed, if you bought a smaller one more paired to it, it will last 30 min or less).

As for your cable issues I'm not sure but I would complain to the provider and have them check your connection, tell them its slow. Has nothing to do with the ethernet cable. I don't know what your friend means by "Change the port" that doesn't make sense.
