The power supply for the HP is 120 volts and I couldn't find a voltage for the card, but I am still looking. I thought to give you the voltage for the HP. Plus, I doubt the card is going to get even half that in voltage. Also, should I change out the fan or just get another one to keep it cool?
I also plan to get a sound blaster card, another gig of ram, and probably a widescreen acer monitor, just for reference to whether I should get this desktop or not.
