I just upgraded my power supply and my graphics card and seem to be having some issues. The computer works fine during gaming but seems to run into some kind of issue while benchmarking. The computer does not turn off completely but the during the heavier benchmarks the monitor goes black and shuts off (the sound still plays though) I'm thinking this may have something to do with an insufficient power supply but I'm not sure. How would this problem manifest itself?
GPU: Asus Geforce GTX 780ti DirectCU II OC
CPU: I7-4770 3.4ghz
PSU: Corsair CX750
Have I underestimated my power needs? or do I possibly have a lemon
