Which discrete graphics card make and model are you planning on using?

Are you planning on using two graphics cards in 2-way CrossFire or SLI mode now or in the future?

For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

For a system using two Radeon HD 6870 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 44 Amps or greater and have at least four 6-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.

Are you planning on overclocking your CPU? If yes, what target clock speed?

Is 2-way CrossFire in your future plans?

What is your power supply budget range?

The XFX ProSeries 550W Core Edition Full Wired (Bronze) (P1-550S-XXB9) would be my recommendation.

^^ Thats a great deal on the XFX.

If you want a little less expensive, here's a decent deal

$34.99 after rebate and promo code EMCYTZT1291

The XFX is even less expensive here:

for about 80 bucks you can get the Corsair TX750. Like the other poster said you only need 500w with 1 card, but going higher on a PSU give you room to change your mind and it will age a little better.
