    My power supply came with a number of power cables. 4 of the cables are "VGA" cables, with one end having a solid 8 pin connector and the other end having a 6 pin connector with a 2 pin connector on the same end (essentially splitting the connector for some reason).

    I connected the 8-pin side to the Titan X and the opposite end 6+2 pin split connector on the PSU. However, my Titan X still has a 6-pin port available next to where the 8-pin connector is connected. I'm curious, if the card interfaces with the motherboard via the PCI-E slot, and the 8-pin connector cable is providing power from the PSU, then what purpose does the remaining 6-pin port serve? What am I supposed to use here? The image below suggests both cables go the power supply? If this is the case, why have a 6-pin AND a separate 8-pin connector cable both providing power to the video card? If that many pins are necessary, wouldn't it make more sense for it to be a single 14 pin connector cable?

    Also, I'm sure this question has been asked before, but while I'm on the subject, can anyone confirm connecting only one SLI bridge is all that is required for 2-way SLI? Are there pros or cons associated with using two bridges on 2-way SLI? I'm thinking the second bridge port on each card is probably for connecting 3-way SLI or greater, but I'm wondering if it can hurt anything to use up both bridges with only a 2-way SLI setup. Redundancy? Handy storage of extra bridge strap? Please share your knowledge.

    Yes, you put both 8 AND 6 pin connectors to card. PCI Express card slot supplies 75W, 8 pin connector 150W and 6 pin connector 75W. Card wants more than 225W, so 6+8 pin is needed.

    One 2-way SLI is all that is needed fort 2 cards SLI yes. That "second" bridge would be useless IMO.
