I was thinking SeaSonic USA S12II 520 Bronze ($70), is that a good purchase?

Seasonic S12 II Bronze 520W review It's a great PSU choice.
It's also a larger percentage of your budget than most builds.

OCZ Fatal1ty OCZ550FTY 550W Power Supply ($70) has a $10 off coupon. Is this one any good for a single ATI 6850?

Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular Active PFC Power Supply ($65)

Antec NEO ECO 520C 520W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply ($60)

Antec earthwatts EA500 500W Continuous Power ATX12V v2.2 80 PLUS Certified Active PFC "Compatible with Core i7/Core i5" Power Supply ($60)

All of those have adequate power for your parts, with room for future expansion.
The Neo Eco 520C is a cousin under the skin to the Seasonic 520 and is probably the best of the rest after the Seasonic itself.

Be sure to take shipping charges, if any, into the total cost picture.
