Weird power...

So yesterday I installed my brand new Asus Direct CUII 660Ti and it's amazing! But my games crash randomly - sometimes I'll play for 10 mins sometimes a few hours and sometimes it wont happen at all. So I set MSI Afterburner running to see if that could give me any clues as to what might be happening when the game crashes. And theres a huge power spike when the game crashes. It says the gpu draws 367% power yet the clocks speeds remain constant and the temps don't rise anywhere above 65degrees. Any idea what this is?
