Hello everyone, I recently bought a second gainward phantom 780ti graphic card and i set up a 2 way SLI. The fact is that now when i play some totally different games my pc immidiatelly shuts down. This happens immidiatelly after the actual game begins and the GPUs start working. The weird thing again is that this happens for example playing crysis3 with ultra settings and 3 monitors in surround or playing red faction guerrilla with only one monitor. The even weirder fact is that this doesn't happen at all playing much "heavier" games than red faction such as left 4 dead 2 with ultra settings and 3 monitors.
What I thought is that it might be a motherboard issue, considering that the integrated audio card is already broken.

I'd be really grateful if you could tell me what the problem might be.

Here i leave a list of my components

Cpu: intel core i7 3930k
Motherboard: Asus rampage IV extreme
GPUs: (2x) nvidia gainward phantom 780ti
Power Pack: Cooler Master 850w GOLD (which should support 3way SLI)

(Sorry if I made any mistakes but I am italian)

Ps: If I didn't miss anything the temperatures should be ok

That power supply can't handle two 780ti's , you need 1000w power supply.
