So not to long ago i got a second Gtx 660 sc although i cant run sli. Whenever i run sli and i go to play any game basically (Anything intense/Stressing the cards) my computer crashes and i dont know what to do. I dont think its my power supply becuase ive tried a 650 and 750 and nothing worked there also ive changed the sli bridges and re installed the GPU drivers. Is there anything else i can do?

Have you overclocked? If so, set everything (CPU and GPUs) to stock speeds.

 

Have you checked your temps? Download CPU-Z and GPU-Z to monitor temps while gaming.

How do you know its not your power supply? 

What type of crashing do you encounter?

I used to run SLI and I encountered crashing due to having too little power... When my rig crashed, it just rebooted itself. No BSOD or anything. 

 

EDIT:

What do you mean you tried a 650 and 750 and it didn't work?

I used a 650 w power supply and now a 750w power supply and didnt change anything i tested it because my cards were using different wattage amounts and that did anything and i did it to see if it was making me get bad performance in sli but it was just the game and my cpu had been bottle necking it and anyways the sli worked on my old Motherboard and cpu but now that i got the z97x Sli gigabyte version Mobo and i5 4690 to stop the bottleneck it hasn't worked
