in the process of putting together my new rig. Im taking my 750tx from my old computer, and i realized that my new motherboard has an 8pin connector instead of a 4 pin. It is labeled ATX_12V_2X4. I've searched around, and some places say you can just use 4 out of the 8, and youll be ok as long as your not doing any heavy overclocking. I WILL be overclocking though, so is this something i should worry about? My board is a GIGABYTE GA-Z77X-UD5H, and i have a 3750k processor with 8GB of RAM. I think my PSU might have an extra 12V 4 pin adapter, can i combine them??? can i buy some kind of adapter if thats what i need to do?
