UPS for my rig

[mhmd shoumar]

Hi,i need a ups for my rig and its not important to last too long(5 min max)so my specs are:i5 4330,gtx 960, Thermaltake smart se 630 watt (87% efficient) Model:SPS-630AH3CCBPSU..
so which of these is the best in terms of price/performance:(PCE 1500 UPS M8 Series 600W (2x Batteries)),PCE 700 VA UPS M8 or PCE 900 VA UPS M8 but i prefer the m8 due to my low budget

M8 should be fine.

Don't forget to also attach your monitor to your ups or have an autoshutdown procedure.

Even with a 630 watt power supply a typical computer with an i3 4330, gtx 960 only consumes about 261 watts with an additional 50 watts for a 24 inch monitor for a total of 311 watts.

Even if you were gaming your hardest you would only be using half of the ups ability.

Of course if you were to lose power i would calmly end my game and shutdown the computer.

I have a 1500VA rated at 800w and I have i5 2500 and a gtx 980 build. There's virtually no load on that UPS, so you can definitely get away with half the VA.

A good rule of thumb is VA = 1.5 x wattage. Read this before deciding on buying a low budget UPS

thx for the info JAcknaylor but is my psu considered a high end..and now i found out why my pc was sometimes quickly shutting down with my previous ups..

Your psu would be considered low grade due to being only 80 PLUS Certified.

https://en.wikipedia.org/wiki/80_Plus

My neighborhood lost power just the other week but my APC BR1500G Back-UPS Pro and Corsair AX860 held up great.

These are great parts to get if you plan on upgrading / purchasing an UPS

AX860 is probably a bit much for yours.

A Corsair RM450/RM550 should work fine, both are 80+ Gold certified.

You could also probably get away with a APC BR700G Back-UPS or APC BR1000G Back-UPS

You misread the article ... it's not about an issue with low end PSUs.... it's an issue with ANY Active PFC-Enabled PSU with a low end UPS.. Those are all low end UPSs

Also, the Thermaltake is by no means a "high end PSU". Un fortunately reviews on the SE model from trusted sites are scare. The Smart series (no SE) didn't fare well at all

Only things i could fine were similar to this w/o any documentation to rely on

However, I was able to track down that it was made on CWTs GPM platform which includes Chieftec GPS-550A8 to 700A8 and Corsair VS 350-650 both low budget PSU lines.

BTW, 80 Plus certification apples to one consideration and only one consideration ... the certification only states how much energy the PSU saves.

xD i have no idea about what ur talking about..u seem a pro but as a final word which ups should i get.

i know that my psu suck but i was obliged due to my low budget and i thought that the psu quality is bullshit and not important.

 

[derekullo]

I would rather have a decent power supply and 4 gigabytes of ram then a shady power supply and 16 gigabytes.

A psu that doesn't deliver the right voltages or currents will cause a system to be unstable at best and damage your other parts at worst.

 

[mhmd shoumar]

thx but i want a ups not apsu ..i know ur right but i need a ups cuz the electricity is not 24/24 so it need a couple of seconds to convert to the generator,so i need a ups that can handle that...since my pc is continuous shutting down of my pc is leading to errors in programs and the shitty blue screen especially in gta5

One that provides pure sine wave output.

PSU quality is only important if you care about the following:

Protecting your components - Does the PSU include adequate protections against line voltage variations, surges etc. Dos it protect the rest of your components if it or any of your other components experiences a failure ... i.e. your CLC dripped water on your GFX card.

Allowing your Components to perform as designed - All of your components have their own voltage control. When voltage drops, current raises in proportion and circuits are rated on the current they can carry. So when your PSU is unable to deliver stable voltages. all your components have to struggle on their own to correct it. The boost features if your CPU / GPU are impaired when they have to struggle to do this. If you overclock anything, how far you can go will be impacted by the stability and quality of the current supplied.

If buying gasoline for your car, would you rather take it from a clean non-corrosive tank or a big ole rusty tank where you can see pieces of steel flaking off ?
