I was looking at the Corsair AX850 but i dont know if the 850 is enough?

Corsair is a nice Psu, 70 amps on the 12v rail.

This is what the graphics card requires.
GeForce GTX 690 - 46A and a 650W PSU minimum ...
It should work fine.

even with all the other stuff that requires voltage ?

Hang on doing the math with power calculator.
