Is 550W Enough?

Here's what I'm running:

Intel i5 2500k 3.30 GHz
EVGA GeForce GTX 560 1GB GDDR5 PCIe Dual DVI/HDMI
ASUS P8H67-M LE REV 3 Intel H67 LGA1155 MB
2 x 4GB Corsair Vengeance DDR3 1600MHz
Seagate 1TB LP Serial ATA HD 5900/32MB/SATA-3G
Samsung Internal SATA 22X DVDRW

And here's the power supply I'm using:

Eagle Tech Voltas series 550W Power Supply

** EDIT ** I should probably mention I'm actually asking this because I'm getting a lot of crashes/freezes while playing diablo 3. The weird thing is my computer will beep right before freezing, which makes me think it might be a hardware issue. I've been monitoring CPU and GPU temps and they're not overheating, so I figured it might be a power supply issue.

Thanks for your help!

  1. The wattage is sufficient, however thats a pretty chinsy power supply. No-name brand, no 80+ energy certification, etc.

    When you say you're getting crashes? are Blue Screen events being logged?

    If so, you can use a program like this to view them:

  2. The game will usually just freeze for about 10-30 seconds, but will occasionally blue screen - restart. I'm not currently at home but I recall a blue screen error saying something like 'kernel data inpage error'. I know a LOT of people are having performance issues with Diablo III so maybe it's not my computer.
  3. Run Furmark and Prime95 to be sure. But, it does sound like a power supply issue... In my experience, it's the power supply 90% of the time.
  4. It does indeed smell like a PSU issue, and unfortunately tconness was sort of off to a bad start picking that PSU in the first place, but I certainly would rather not tell someone to run out and buy new parts without confirming they are the causal factor. I would run memtest too on top of prime 95 and furmark, and if possible try swapping in a known good power supply first.

    If Diablo is the only game the problem happens in, then try a clean install of the game.
  5. Any recommendations for a new PSU?
  6. Sure:

    Kind of pricey, but very well made 5 year warranty:

    A little cheaper but sufficient 2 year warranty:
