Help with sli GTX 580 shutting computer down

post #1 of 2
Thread Starter 
OK so my friend has a i7-860 with an EVGA P55 FTW 200 Motherboard, silverstone 1000w and had one evga gtx580. Everything was going great and he found a sweet deal on (2) gtx 580's for $250. He put an extra in his computer for sli and the other in his wife's.

Anyways long story short drivers are updated and everything was running smoothly until they are put under a heavy load. Once under load the PC will just shut down. No blue/ black screen or errors just shut down.

Why is this happening? Is it overloading his PSU? Or dies it sound more of a heat issue?

He did some temperatures with a thermometer and they seem to be within thermal limit.
