Mobile site must be weird, I typed out a paragraph explaining this. I am trying to connect my GTX 770 to my EVGA Supernova 850 G2. The 770 needs 2 8pin cords. The power supply came with one 6pin next to a 2pin and another cord that looks like a 6pin and 2pin, but has another cord coming out the back of the 6pin and 2pib, which ends in a 6pin

I remember this confused me for a minute also when I was hooking up my GTX 770. I believe I used the included dongle for one of the power inputs and I ran another cable direct from my supply. I can check tonight when I get home.

So your power supply has (in total) 4x 6+2 pin connectors (on the right) and 2x 6 pin connectors (on the left)?


The 6+2 pin connectors (on the right) can be used as 8 pin connectors (6+2=8), just use those. No need for any extra adapters.

I'm talking about in total, not per GPU. You should have four cables, that have (again, in total) 2 of the ones on the left and 4 of the ones on the right. If you don't have that, you have not connected all of the required cables that came with the power supply.

Check out this neweggTV overview video on the EVGA 850 G2. At around 3:50, the "actor" grabs 4 PCIe cables into the picture. These are the four that you need. Each one will have 2 8-pin ends. The non-breakaway ends go into the PSU and the breakaway ends (6+2 pins) go into the GPU. Unless you bought this off of Ebay or something, you will have 4 of these cables in the packaging.

I also remember having the thought, " how the hell did that just confuse the crap out of me?!" after I had it hooked up and running.

The 6-pins go nowhere (just leave them hanging freely) and the 6+2 pins can be connected to the graphics cards as if they were 8 pins.

Ok so that answered that question, but each 770 needs 2 8pins, so should I use the VGA 1 and 2 port for the first graphics card and the 3 and 4 port for the second graphics card?

AHHHHH....I see now. Those 2 6 pin cable are not dedicated cables. You can use them as either 2+6 or just 6 pin :pt1cable: . Just ignore the 6 pin as you need the 6+2 for the 770.

Yes, that's exactly what you should do.
