yep, even a 500W is enough for that :D 


Well newegg.com says it needs 575W PCI Express-compliant system power supply with a combined 12V current rating of 42A or more. I know its enough wattage but what about the Amps? How can I tell if the PSU has enough?

Look at the 12V rail.

Theres 3, two at 22A, and one more at 25A. So do I just add those together?

It has combined 540 watts for the +12 volt that gives 540/12 = 45amps constant load on the combined rail

So just barely enough to run it. Thanks, I believed all of you, just wanted to understand why.
