Well crap, I just realized my 2 GTX 680s each have 2 6-pin connectors. I have the Booster X5 coming in tomorrow but I understand that it has 2 6-pins and 2 8-pins. Are there 8-pin to 6-pin adapters or do I just run the 6-pins of one of the cards off my mobo? Either way, if there are 8-to-6-pin adapters, is there one you recommend? Are there specific mono-to-6-pin cables you recommend? Thanks for any help on this!
