Beyond a minimum nominal wattage required to run the components in your system, PSU design and quality are more important than raw numbers.

There are a lot of "popular" front runners out there, such as enermax, antec, pc power & cooling, etc., that are decent enough, but be sure to check out the reviews for fortron and seasonic... consistently rated as two of the best.

After researching this rather extensivley I settled on Seasonic for my new rig. I bought the 650, with the idea that I may eventually SLI my 8800GTS. The Seasonic can easily handle this, where-as you might have to step up to an 850 or better with a lesser brand PSU... and even then you might have problems pulling enough amps on the 12v rails.

The Seasonic is probably the most efficient PSU out there as well. Aside from "green" considerations, that translates into less heat. The only negative is that neither the fortron nor the seasonic PSUs have modular (unplugable) cables.

Edit: it seems Seasonic does offer a modular PSU now. Pricey however.... $200+ for a 700w unit.
