I just got a gtx 680 and am upgrading from a 5850. My power supply has 2 6-pin power connectors but the new card has an 8 pin and a 6 pin. It came with an adapter which looks like it takes two 6-pins and makes it one 8-pin. How should I connect all this?
Edit: I just found a connector which is a 6-pin with an additional 2-pin on it which says pci-e. Shuold this go to the 8 pin?
... sigh, and how many people who know how to use this product have not been able to purchase it yet? lol
Anywho, yes, the 6+2pin connector will serve as your 8pin, and then the 6pin connector will go in the other slot. More important than the connectors is the power rating, and the quality of power supply (bigger is not always better, nor is it always adequate). But assuming it is a quality power supply, and meets the requirements set by nVidia on their site, then you should be good to go.
