I bought the asus h97 plus and evga supernova g2 850 watts power supply, the problem is that the motherboard requires an 8 pin cpu connector, but my psu cpu cable has one 8 pin which has to go into the psu and the other end two four pin connectors, but one of the two four pin connectors dont match my motherboard making it a 4 pin connector, what should i do? My cpu is i7 4790k.
