Pc shuts down when playing on 3 monitors

I just recently installed another GTX 770 for sli and whenever I try to play an online game with nvidia surround my pc restarts? I think it may be a psu problem.

Only Corsair's HX, TX, AX units are great. Stay away from the others.

Thanks a lot!! Il be going to get that and see if it works

What I don't get is monitors aren't supposed to increase power consumption right? Is it just making my gpu work harder and power starves?

The monitor does not use the PSU at all. they draw power from the wall.

One 1080p monitor does not require your cards to run at 100% but three will thus increasing the amount of power the GPUs pull.
