Actually the 7770 uses the least amount of power.

The GTX 550Ti and Radeon 6850 will use substantially more power than the 7770, the 7770 only needs the PCI-E power connector for all of 10watts, it uses ~85watts at load. The 6850 and 550Ti on the other hand both cross the 100watt barrier and both use around the same at load. Performance wise the 7770 or 6850 will run circles around the 550Ti, it just can't compete to the AMD cards. Also the new 7000 series from AMD uses less than 10watts of power at idle.

In this price range you're better off getting something from AMD if power consumption is a concern. Alternatively, you could wait a few months and see if NVidia releases a replacement for the GTX560 or GTX550 using their new architecture.

From the cards you listed, I'd get the 7770. You could actually get a 7750 which doesn't even need a PCI-E power connection and uses ~60watts at load.

The power supply you listed is fine, but I would get something from Antec, Seasonic, XFX, PC Power and Cooling, or anything that uses a Seasonic platform. The new CX series from Corsair was made by FSP and has some ripple issues. Try looking at the Antec High Current Gamer 400 or 520, Antec Earthwatts 430, Seasonic S12II 430 or 520, PC Power and Cooling Silencer MKIII 400 or 500, or the XFX Core Edition PRO 450 or 550.

Thanks and I hope this helps.
