Links 1-4 don't work...

Are you planning on Crossfiring? How many SATA devices are you planning on running? Are you overclocking? All of these factors influence how much power you need, but other than the first one, don't really affect the PSU size too much.

I highly recommend sticking with Corsair, Antec Earthwatts or OCZ units. Without knowing about Crossfiring, I'd recommend the OCZ StealthXStream 700W. It's $80, with a $25 rebate, and is a high quality unit that will handle Crossfiring.

If you're not Crossfiring, you probably only need 500-600W. Just find a unit by those manufacturers, and you'll be fine.

Your links are broke.

Do you ever plan on adding another 5770 in Crossfire?

If not, I would recommend this one:

Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply - Retail $49.99

Keep in mind that the above PSU doesn't include a power cable. It's not usually a problem, but something to keep in mind.

If you want to keep the option of Crossfire open, I would recommend one of these:

CORSAIR CMPSU-650TX 650W $89.99 - $10 MIR

Antec EarthWatts EA650 650W $84.99

OCZ ModXStream Pro OCZ700MXSP 700W $99.99 - $30 MIR
