You don't have to meet those Amp requirements as that is not how power works.

The amerage value you see is how many amps the PSU can safely output on each rail. Components only draw as much power as they need at the time.

You're fine, that PSU will easily be enough for any of those setups.

i disagree otherwise found here@http://www.evga.com/products/moreInfo.asp?pn=01G-P3-1563-A1&family=GeForce%20500%20Series%20Family&sw= section here@
Requirements
Minimum of a 500 power supply.
(Minimum recommended power supply with +12 Volt current rating of 30 Amps.)
Two available 6-pin PCI-E power dongles
it says otherwise

Those "Requirements" are really just recommendations based on what the average 500w Power Supply is like.

It really depends on the power supply, and for graphics cards, how much amperage is on the 12v rail(s)

That unit you picked out is a good unit and a fine choice. It'll run two GTX 590's if asked.

NVIDIA and AMD's power supply recommendations are including peak-rated units. We here at OCN recommend quality, continuous-rated units.

We will also never lead you in the wrong direction. smile.gif
