Yeah, it should be enough unless it's an el cheapo PSU. What power supply are you looking at? How many amps are on the +12v rails?

+12v1@14A,+12v2@15A,-12V@0.3A

Low amps for a 550w...the FSP I have right now can run an 8800 though.

I'd say the 500W FSP mentioned above is good, although there is no PFC and the efficiency isn't the best.

That is cutting it pretty close, but you may be able to get by. I think the GTS wants a combined 26 A on the 12V rails. That has 14 and 15, which does not add up to 29 A. To be honest, someone else will have to figure out how to add them.
