Pc reboots after running occt gpu stress test

Hi everyone, so I just got a 560 ti running in my desktop with the following specs:

gigabyte 965p ds3
q6600 @ 3.2ghz
4g of 800mhz ram at 712mhz , an 5,6,6 timings
4 hard drives
400w fsp blue storm PSU
and of course the 560 ti

The 560ti replaced a 8800gt.

When i run f@h and BF3, my pc runs fine with the gpu temp at about 65 - 70 degrees.

However the moment I start the occt gpu stress test my pc restarts with no BSOD.
It just restarts.With the 8800gt this never used to happen.

Can anyone give me any suggestions on what the problem might be?
Any help is appreciated.

    I second that. At least have 550 (decent brand) with the 80 watt power rating. Since you have so many other items, maybe 600-650 watt? I had a system in the past restart on its own with no warnings, and the thing blew up eventually and needed a replacement.

  4. Thanks for the fast response . It looks like I have to go spend another 50-80 bucks during the Christmas season.
