I just bought a eVGA fx5900se and i was wondering if the power supply cable is really required to go in the video card? i only have a 300W power supply is that enough?? if i buy a new power supply is there a danger to my pc? never done this before.
Changing out a PSU is rather simple as well. Unplug everything, remove the 4 screws then put the new one in and screw it back in. Plug everything back in and jump for joy!
