What is "EZ Plug" supposed to do? My old motherboard has a 4pin molex attached to it and my psu had a female that attached to it. On my new motherboard there is no EZ Plug (4 pin molex) on the mobo. Should I just not worry about it? I feel like this could be for voltage for sli but my new mobo doesn't have more then 1 pci express slot now.
