specs-Coolmaster UCP 900w and the motherboard is crosshair III formula.
I have the 24 pin plug connected but what do I need to hook up to the EATV 12v plug on my mobo? It is a 4 pin slot but has a blk cover over it making it a 8 pin if needed. I really need help with what to hook up to that 4/8 pin slot.

Your psu has a 4+4pin power connector for that slot. Since you have 8 pins, take the cover off and plug in the whole thing.
You could break that 4+4pin in half to use on other mobos that aren't as friendly as yours is.
no 8 pin combo from the psu fits the slot so will 1 4 pin be enough ?
