i would contact hp and see what psu you could upgrade to...........if ya wanna figure out what ya need yourself, here is a very good wattage calculator...........plug in your specs, and the card ya wanna get, and it will give ya a really close calculation of the wattage ya need..........http://www.extreme.outervision.com/psuca...
