Im some what new to building a pc question on PSU unit plugs. I bought the OCZ Z series 850w psu.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Cables already attached are the 24 pin for motherboard im assuming.

Has the sata connectors for drives etc..

Than remaining cables already coming out of the PSU are an 8 pin and two 4 pins. Assuming the 8 pin is for the CPU. Not sure what to use the other two 4 pin connectors for.

My GPU is the

and it requires an 8 pin and a 6 pin connector. Im just honestly not sure which cables to use and which 12v rail to use on my PSU. ?

Do I use the two extra 4 pins to my 8 slot on the GPU. or just leave those alone and use the yellow 8pin PCIE cable that came with it and another PCIE yellow cable and break away 2 pins for the 6 connector? Than just not sure which rail to use??

Pleas help, thanks

It is a single rail power supply.

Just connect the 6+2 and connect and another 6+2 and use those to run the video card. The cpu should be fine with the 2+2 cable, you can tuck the other one away as you do not have a board that needs it(or use the 8 and stash the 4+4).

its a single rail psu so you don't have to worry about that, as for the cables, read the instruction manual for the safest results

ok so Just take 2 of the 6+2 cables that came in the bag and use those for the GPU? and it doesnt matter which yellow plugs I use on the PSU? like two on top next to eachother or do I use the one on top and one on the bottom? Just dont know If I mix the differnt labled voltages or use the same pairs?

All the yellow plugs are the same, 2 are just upside down. Since the power supply is single rail, it does not matter what 2 you use.

As for the 4+4 vs 8. check this

Some ultra high end boards have had 2 x 8 pin or an 8 + a 4 to provide extra power for overclocking(or multi cpu socket boards.).
