  1. Yeah, that'll be fine.
  2. I do not recommend it Cooler master is known to be one of the worst supplier of power supplies only the silent pro series are reliable the rest has been proven time and time again to be garbage!Here is Guru3D's power supply recommendation:

    Radeon HD 7770 - On your average system the card requires you to have a 450 Watt power supply unit.
    Radeon HD 7770 Crossfire - On your average system the cards require you to have a 550 Watt power supply unit as minimum.

    If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

  3. The 7770 barely needs more than 75 watts. more watts is always better but 500 is more than enough.
