Hi all, I have an old xeon macpro (dual 2.26ghz). I also have a 2nd hand geforce gtx 9800, I'd love to install it, but the cards need two six pin power leads. 2 problems.... I don't have any spare leads, but I can't actualy find where to install the power leads, I'm not even sure how to access the PSU? Can anyone tell me if it's possible, or what I need to do to make it work. Btw, I mostly use this Mac with vista, so drivers should not be too much of an issue for me, it's just getting it plugged in and powered. Cheers!!!
