Looks like I have hit my second casualty with folding. Have not trouble shot much yet but my guess is one of my 470's is the cause. The computer will run for about an hour before restarting when not folding, as soon as I crank up the CPU and twin 470 I don't even get a minute before restart. I did pause both GPUs and let just the CPU run and it did not restart, (temp looked good) that's what leads me to believe it is one of the GTX470.
I have a 850 watt PS (corsair) I think that is enough power. I have been running with the two GPUs folding for over a year off and on so I am eliminating that for now.
So with that said I think it is time to remove my two space heaters and get something more efficient and powerful. Any suggestions? I do game on this computer too so want that performance to stay up. Lets say the $300 range.
