RIG Setup

Q6600
EVGA 790i Ultra
2 GTX 260's SLI
4gb DDR3 Corsair
Corsair TX-850 PSU
5 Seagate HD's
Hauppauge TV tuner
Vista 64

The entire rig is about 1 year old except for the CPU. While the PC is idleing or doing very little its fine. When I play supreme commander, sins of a solar empire or anything that requires some hardware usage, the system instantly restarts. I get no BSOD it just restarts instantly. Which is why I think the PSU is the problem. Its as if the PC just restarts itself. I've forgot to turn on my vid fans all the way, and when those overheated they typically turn the screen into 1 color or multiple colors and then it just hangs. My problem is the computer just restarts.


I down clocked everything right now and am running prime 95, which has been fine now for 5 mins. I'm wondering if its the amperage draw of both gtx 260's which killed the psu. I've had both vid cards and the same psu since around January of this year.
 
The TX850 is more than enough for your needs. It's possible that if you have a faulty unit you overdrew from the PSU and it shut off. However, it should not have its OCP at a level low enough that your system would trip it, and if the PSU failed for another reason it would probably be dead.

That basically leads me to believe that you have a stability issue. I've seen random reboots happen many times as a result of that, so I suggest that once you're done priming, try doing the same things you were doing before that caused your PC to reboot, while keeping all your hardware at stock speeds and voltages.
