Once again, for the millionth time, wattage on a PSU is
insignificant.
You need to worry about the
amperage on the 12V rail.
Suggestions:
Corsair 520HX
or
PC Power & Cooling 610W
Remember, the Corsair has less amperage but MORE 12v amps, 54 to be exact. The PC Power & Cooling has more amperage but LESS 12v amps, 49 to be exact.
Pick and choose, hope you make a good choice.
