UPS suggestions?

post #1 of 2
Thread Starter 
Hey guys..

I'm on final stages of my build. Waiting for my Corsair AX1200 RMA to be sent back when it hit me - I should probably have a UPS for this thing. :-)

Any suggestions? How do the power calculations work out for PSU vs UPS? Do I need something that will support at least 1200w?

The only brand I am familiar with is APC. Good experience w/ them in the past and at my job, but wanted to get a second opinion before I committed to anything.

APC are definitely quality and respected. Basically what you want is a UPS that can supply eh maybe 150% over what your machine can draw from the wall (at load). The most accurate way will be to test load with something like a kill-a-watt and see how much power your rig actually uses. Hmm.. that machine might need a pretty beefy UPS.

So if your rig can pull 900w from the wall, then you would want a UPS that is capable of 1500w load or so. EDIT: Actually looking at the spec sheets for the UPS it looks like they can run off full load for a few minutes, so if you wanted to just a ups that was a little bit over your max draw, it would still be able to run just long enough to safely shutdown itself.


I know the 900w variants of UPS go anywhere from $120 to 200+ I think you may be getting into business class with a 1500w+ UPS, which may be in the $400+ price range.

I've had good experience with Cyberpower and APC. Cyberpower being a little cheaper, but with generally the same features and works well.

Even if you go 30-50% over your psu draw, you will still only have a few minutes to run the machine at load, maybe around 10-15 at idle I would guess. That is about how it works out with the smaller UPS.

This list shows what models support what loads (use the drop down select the load and it will show available models and how long they can run). These are just APC's
