Running furmark on 6000x1080 I cud hear the fan spinning faster but not much else
I checked on a test review that my psu has a safety function that turns it off at 940 watts.
To reach the psu limit I had to run several furmark tests at the same time, as the cpu wasn't working more than 30% I run meanwhile a cpu test that brougth all cores at max.
So I had 4 gpu at max and the cpu too.
So the fan began spinning at maximum and after a few minutes the pc turned off.
Even if in normal stressed conditions it works I would eventually go for a higher, like 1000-1200 psu. If you wanna oc the cpu 850 is definitely not enough.
If you live in center europe, today evening I knew a guy that has to sell a 1200 and a 1500 psu.
By the way I just sold my two gtx 680, made a good sell, I now wait for the titan card Edited by qiplayer - 2/13/13 at 3:40pm
