I think a quality 850w PSU is going to do the job, a corsair 850w probably will.

Here are the ATI recommended power supply requirements for systems with the ATI Radeon HD 5770 and 5750 video cards:


450 Watt or greater power supply with one 75W 6-pin PCI Express® power connector recommended

600 Watt and two 75 watt 6-pin connectors for ATI CrossFireX™ technology in dual mode

Corsair, PC Power & Cooling, and Seasonic all have excellent reputations for high quality power supplies that are reliable and stable. They consistently earn high marks in technical reviews and come with a 5 year warranty.
