Do I need a new power supply if I add this graphics card?

Solution
what graphics card did you have in mind? yes, thast likely a crap power supply. obviously powering a hd 6670, but if you bought it prebuilt, then thats literally all its designed to handle. watt is actually not really important, when choosing a graphics card, make sure its of good quality (high quality components), and a +12v amp value that is high enough for a more powerful graphics card.
