Oh, my goodness. I’m a doofus. I was using the wrong cable. Did I ruin the whole thing by trying to turn it on so often?
All I did was cut the sleeve that keeping the 10 pin and the extra 2 pin connector together, so I could get the smaller one the cpu power.
I still find that this cable is too short for me to snake around behind the mobo and it just dangles in front, which I don’t like. Is there a better way?
