More about power supply help
  1. 450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for AMD CrossFireX™ technology in dual mode).

    ^ Taken from the AMD website for a build based around a 6770.


    Recommended PSU brands include: Corsair, Antec, XFX, SeaSonic.

    This 430w Corsair unit would be about right and theres a great rebate price currently at just $25 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026
  2. so if the graphics card recommends a 450 watt then should that not be what i go with not a 430 is not to low?
  3. Corsair makes very high quality PSU's that deliver the power they state they do.

    Generic cheap PSU's might say they are 750w, but only actually able to deliver 450w for example.

    Corsair 430w unit would be fine for a build with a 6770.
