Hi everyone. I bought a Radeon HIS 7950 card for my Mac Pro. I am pretty sure that it is a PC version, but except for the lack of a boot screen, it should work. It didn't come with power cables. From what I can tell, I need a pair of 6-pin male to 6-pin male cables, but I can't find any on eBay or computer suppliers websites. Is there something obvious that I am missing?
