Hi!

I just built a new pc. I got a Gigabyte 850W UD850GM PG5.

The cpu power cable connects to 8 pin on the PSU and have two outgoing headers (Split cable?) going to either 8 pin or 8+8 pin.

Should I connect both 8 and 8 pin on the motherboard with ONE CPU 8 pin EPS cable? Im thinking that maybe I need another 8 pin to 8 pin PSU EPS cable to connect to the other 8 pin on the MB?

Sorry for the confuse... Please help! I know its probably not needed to plug 8+8 pin on MB with my CPU but if I can to increase stability or OC I want to. I have read the manual of both PSU and MB and cant get my grip on if ONE 8 pin cable is enough to benefit from 8+8 CPU MB connection...
