Hi, i recently found an old Asus DirectCU II GTX 580 and i was planning to put it in an old desktop pc lying around to make a quick half-decent gaming pc. When checking if the pc had the correct power cables, i found out that there were only two pci-e 6 pin connectors while the 580 requires two 8 pin connectors. What can i do? Is there some sort of adaptor i can use, or do i have to bu an 8 pin connector? Any help would be appreciated
