The one thing I can't figure out is why BFG is still supplying the double 6 pin to 8 pin connector (instead of just a single adapter). It requires two 6 pin cables from power supply to convert to single 8 pin. That means for a power supply that only has 6 pin cables, it takes 3 of them to run the card. A simple single connector 6 pin to 8 pin adapter can be bought to convert this (I bought one). The extra two pins are only grounds so a double connector is not necessary and could be a problem with a power supply that only has two 6 pin connectors.
