According to Gigabyte, 31amps on the 12v , more than enough

Of course. You can even surely get away with a 350 W PSU, and I factored in upgrades even with that! And I assumed you wanted to keep it 4 years!


This power supply is more than enough.

+1^^
The HD 7770 only consumes around 80W totally maxed out. That's about 6.7A max. That leaves plenty for the rest of your system.
