PC shuts off randomly while playing games, new gpu

Im having a problem with my pc, I just recently got a new graphics card (EVGA GTX660 SC) whenever i play an intense game graphics wise, after about 10 mins or so my pc will shut off. I found out what the temperatures were when my pc shuts off and my cpu and gpu never reached higher that 60 degrees c. I was wondering if anyone could shed some light on what is going on. My PSU is a PowerPlus 500w. Any help is appreciated

  1. I would recommend replacing your power supply, which i'm assuming you agree with. Purchase a 650 watt power supply, preferable a Corsair or Antec. I've been using these drives for years in all of my client computer builds. Just because your power supply says it is rated at 500w, doesn't mean it actually runs that high, ever. Look at purchasing a silver, gold or platinum rated power supply.

    Make sure that all power connectors are attached properly. Try using one of your other power connectors. Also, the specs for that vid card are:

    Minimum of a 450 Watt power supply.

    (Minimum recommended power supply with +12 Volt current rating of 24 Amps.)

    Total Power Draw : 140 Watts


    Make sure your 12V rail is rated for 24A. If you have a spare power supply, try using it.
  3. Thanks for the speedy reply guys, i checked out my power supply again and the 12v rail is only 20A so i will be needing a new psu. Do you have any suggestions as to which model of Corsair or Antec i should get? Thanks for your help!
  4. I like Seasonic power supplies, but Antec and Corsair are good also. Try to get a PSU rated at least 80+ (bronze or higher, preferably silver or higher) and has active PFC.
  5. Okay, thank you very much for the help guys!
