Power Supply and Video Card
I'm looking at this computer :Gateway DX 4860-UR10P.PTGCPP2.017, on tigerdirect. It says that it has a 300 watt power supply, but an integrated video card, I want to add a ATI Radeon HD 4550, now the card specs say it needs a 300 watt power supply. Would I need to buy a better power supply to support this card, I figure the hardware in the computer is already using an amount of the 300 watt power supply, and the card would use the full amount of the 300 watts. Any suggestions, would this work?
