Got a new GTX 770 2GB DirectCU II OC. The system crashes when I attempt to play a game.

I was using a 600W PSU with 34amps on the +12v rail when the system crash occurred.

So I got a new corsair PSU with 750W with 62amps on the +12 rail, but it doesn't fix my problem?
Do I need to Flash my Bios ?
I have a feeling that the GTX 770 isn't withdrawing much power as it should/

I calculated my overall power supply, im using an average 550W
