That PSU should be fine, I'm unsure 100% of the power draw of the 5770, but I'd imagine a 400W Corsair unit would be fine. Someone else who's more sure would need to chime in. If you do have a bit more in your budget, You could pick up something a bit bigger just in case the itch comes in to upgrade to a 5850 or something later on. Other than that, everything looks fine.
