NEED a UPS for a gaming PC

The best suggestions for UPS depend on how long you want battery backup to run and your budget. Two of the best UPC companies right now are APC and Cyberpower.

This UPS will almost certainly be everything you would need for a personal rig:

-APC BR700G UPS Pro ($110): http://www.newegg.com/Product/Product.aspx?Item=N82E16842101381

If $110 is too high I would recommend these APC models in decending order:

-APC BE750G ($85): http://www.newegg.com/Product/Product.aspx?Item=N82E16842101311
-Cyberpower CP750LCD ($75): http://www.newegg.com/Product/Product.aspx?Item=N82E16842102146
-APC BE550G ($55): http://www.newegg.com/Product/Product.aspx?Item=N82E16842101343
 


Actually you need to be careful with UPS recommendations. I was shopping for an additional one a few months ago and discussed with both APC and Cyberpower about this. The problem for example is the last one, it maxes out at 330w. I assumed (incorrectly) that if its not on the battery then if your system draws say 600 watts then you are fine. Turns out I was wrong and both APC and Cyberpower told me that trying to draw more power than its rated for, even when its on wall power, can cause the UPS to shut down.

When buying a UPS you need to figure out the maximum draw of your system (thats not necessarily what your PSU is rated at, but approximately the most it can draw) and then buy a UPS that can provide that amount of power. Then of course if your power does go out, make sure you stop gaming immediately to get the most out of it (usually 15-20 min).

Based on the fact he says he has a gaming PC, and the specs posted, very likely all of the suggestions so far may be a bit too small. Something like this may be more in line with what he needs:

Good point, the last APC would almost certainly not cover his max potential draw.

A 1000V would absolutely do the trick, but with a 620W PSU I was trying to hit the 700W models as much as possible. Great facts to keep in mind though RL, and a good PSU suggestion as it is still in the same price range as the APC 700 Pro.
 


Actually APC naming isn't in watts but in VA, so the 700 Pro is 700va and 420w. 420w would probably work for him, but may be a bit low, especially if he ever decides to upgrade.

I made this mistake, my system draw at full tilt is 603 watts, and I have a 600watt UPS. Mind you it only spikes to that and when gaming it hovers more around 500, but if I could do over I would go bigger (yeah I asked the questions in my previous post AFTER I bought and started using it!)
 
What's the brand and model of the PSU?

Some PSUs won't run on a non-sine wave UPS. If the PSU's Active PFC circuit is incompatible with the UPS' waveform (e.g. simulated sine wave, stepped approximation to a sine wave, square wave, etc.) when operating on battery power the UPS will fail to properly switch over to battery backup mode during a power interruption.
 
i go with APC BR1000G-IN cannot go bad with it... but do not go with indian brands like iball, VIP etc.. cheap componants can fry out your rig..

Formula : TDP of your rig + 20% incr. for PSU + 20-25% incr. for UPS follow as much as you can..
 


Its not that it will fail, but that the PSU will lose power and then power up again. Unfortunately it acts the same as if you hit the reset button which is not what you want.

I contacted EVGA regarding this problem as well. They told me the problem is not as prevalent as people think and that they believed my PSU would not have an issue with either one, however I went with a Sine Wave UPS "just in case".
 


Some UPS', that are incompatible with a PSU's Active PFC circuit, will actually report an overload condition and fail to switch over to battery backup mode. Some UPS' will even make strange groaning noises when attempting to switch over to battery backup mode.
