I need to add an HD 5770 to our Mac Pro G5. Currently, the video card in there is only powered through the PCIE bus. Seems I need a 'special' cable to get the 5770 power.

Does this look right? From what I can tell, the motherboard supplies the power using that cable to the card. If Newegg sells one, that would be cool too.

Thanks

And for the record.>> I am no Mac person. This is a work computer.

More research shows that the Mac Pro 1.1 can only take specific Mac graphics cards? Help?!
