    How much does my PSU need power?
    Is 400W enough?
    What are your recommendations for a PSU?

    The "Radeon HD 5770" calls for a 450W PSU.

    My opinion on a PSU has always been get at least 100more watts than you need to have plenty of headroom on a gaming rig. Since you have an 8320, if you plan on overclocking and putting possibly later another high end GPU it would be wise to leave some room. I would recommend getting a 550watt or a 600watt to leave you ample room for upgrade in the future and keep your system smooth.

    And it is my opinion that AMD already allots plenty of headroom. After all neither AMD or nVidia wants anyone burning up components, because of power supplies ratings. I will however mention having extra power never hurts.

    Well, it's not hurting per-se, but if you over-compensate a power supply you risk not being in the ideal power delivery curve, and it'll cost you more in electricity. ;)

    I think >550W is really safe for future upgrades.
