Possible Power Supply Upgrade. Need Advice.

Hello,

While recently playing GTA IV on my recently upgraded desktop (1-2 weeks ago), the computer shutoff after about 10-20 minutes into the game (no BSOD). About 2 seconds after it turned off, the computer turned back on. From some other research that I have done it seems like it is probably my power supply which is a Diablotek 600w PSU (from what I have read it is an 'awful' PSU). My first question is whether or not the issue is actually the PSU? I have played other games for several hours (Battlefield 3, Far Cry 3), without the sudden shutdown happening. My second question is what the title of the post says, what PSUs would you recommend for my current set-up (specs at the end)?. My budget for is probably around $50 - $90. I will be gaming on the computer and currently have a gtx 660 installed. In the future I may add a second gtx 660 for SLI, so the suggested PSUs should ideally be able to handle the upgrade. Also, as far as wattage goes, what would be the ideal wattage that I should look for in a PSU, both with and without SLI? Thank you very much for your help.

I have been doing a little research and here is a list of PSUs that I have come up with so far:

  2. I'd go the Seasonic, plenty of power, room for expanding your rig, and prob good if you move to a newer rig in a couple of years, Seasonic is among the best
  3. Thank you guys! New PSU is on the way :)
