This is not an issue, I am not using an adapter between the video card and the power supply.
I am currently using the video card as we speak, but the CD won't install the drivers so I can't play AH and simple things such as scrolling a web browser just doesn't run smoothly. So it is putting an image on my monitor, I would assume it should recognize the ATI Hardware yes? When I turn on the PC, it says I have new hardware I need to install.
It may be an issue. At least make sure you plugged two different lines to the adapter. You can _not_ use two molex from the same string of cable coming from the power supply.
Crossfire was first time published with the x1950pro and it was experimental + buggy. I would not hold my breath on getting it to work on that old card.
I really don't understand why you got a card that old anyway.
