This is your result : Recommended PSU Wattage: 371. From this result an 450W psu its enough.

That is an aproximate power what your PC can use . For my PC is calculated 405W. If is calculated 413 W then an 500-550W psu is enough for your pc.

For a system using a single Radeon HD 5770 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 22 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

The most critical power supply specification is its combined +12 Volt continuous current rating not its total wattage.

Even the new Antec EarthWatts EA-350 Green, with its combined +12 Volt continuous current rating of 27.5 Amps and one 6-pin PCI Express supplementary power connector, is capable of properly powering a system with a single Radeon HD 5770.

Nowadays a 6-700watt will do the trick for any singular video card setup and basic computer layout. I usually go overkill to make sure I am ready for any future upgrades. Myself, I would shop for an 800 Watt just in case I need it later. But 600 Watt or more should be safe and cheap.

My system with a PII 955 and a 4850, which uses more power than a 5770, draws less than 350 W from the wall under load, a 450-550W unit will be fine, if you want to do crossfire down the line pick up a good 650 W unit now.
