The amps on the 12v rail(s) is more important than the watts. Look at that first. And yes, the PSU's listed so far are all good.
 
For a system using a single GeForce GTX 480 graphics card nVIDIA specifies a minimum of a 600 Watt or greater power supply that has a combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one (6+2)-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.
 
480 power
Card/System
Idle - 51 / 190 Watts
Load w/Furmark - 94 / 420 Watts

So Yes any quallity 500->650 Watts is good for single card, If thinking of going SLI then consider 650 Watts as Min.

Hoping that the 480 performs better than a 6870 as total loaded system power (i5-2500k) is only around 350 Watts.
