What is your PSU Make & Model?
Cooler master RS-700, I figured it out I think. The 2x2 on the 10x2 goes under NOT over, so it fits. Now, the 4x2, I could use a 2x3 with a 1x1 (ground) or two 2x2's for power. After reading about the pins , I found that I needed 4(+) and 4(-) so the 2x3 with the 1x1 ground wouldn't work I figured.
