XFX PRO 550W CORE EDITION (forgot to put xfx on the title)

I won't use a GTX770, but probably a GX870 (when it releases) Will it be enough? The only other PSU that seems decent in the shop I'm going to buy is the Corsair VS 650W.

This is the site. If you want to see. It's in Portuguese though. http://www.pcdiga.com/1/94/Fontes

Thanks
 
The XFX Pro 550 delivers 528W on a single +12V rail, so it should be fine. The recommend PSU for a GTX 770 is 600W, but this has to account for the crappy no-name PSUs that don't deliver the wattage they claim.

Both PSUs will do a god job, but I'd prefer the Corsair to give myself some extra headroom.
