The 6 wire cable works just fine. I was a little cautious and was matching things up exactly. It works wonderfully. Thanks all. 
I just purchased a 850w PSU to upgrade my Aurora R5 with a 460w. It came with all wires. While matching up all wire connectors to make sure it would work I noticed that 850w wire for the mother board MD63V with the eight pin connector has 6 actual wires in the 8 pin connector while my original 8 pin connector has only 4 actual wires in the 8 pin connector. Are the extra 2 wires ok or should I cut them? I don’t want to fry the MB. Example MB pictured below  [IMAGE]Example mother board
