  1. More than likely yes, that should be enough. You should post what card. You can also look on that manufactures website for a minimum wattage requirement.
  2. 300w will run a graphics card that does not need a auxiliary 6 pin power lead.
    If you install a more demanding card, it will not run.
    a 550w psu of good quality will run a card as strong as a 7970 or GTX770.

    the card that i am getting is a sapphire 7850 OC 2GB .... is it possible that i add two power supplies to my computer or will the 550W run my card and my computer fine .

    my system is :-
    intel core i5 2400k
    8GB RAM
    500GB HD
  4. ^ Stress the "good quality". Not all power supplies of equal rated power are the same. Some exaggerate while other outright lie. Tell us where you shop and a budget and we'll pick you out a good one.

    BTW if geofelt says something ... good idea to listen.
    one quality psu is the way to go.

  6. A decent 550w power supply should be more than enough. I'm running my 7850 off a 380w power supply right now. Make sure to try and get a power supply that is at least 80+ certified or better.
