I have a ? that I hope someone can answer. Why is the PCIe set up like it is? A 6 pin connector has three 12 volt wires and three grounds and a 8 pin has three 12 volt wires and five grounds. It's just two additional grounds? I don't get it. Why not have one 12 volt wire and one ground. Saves production cost. Reduces clutter. In addition to this I have had to splice PCIe cables on one rig and I am amiss at the puny aluminum wires that the three 12 volt wires carry. I wouldn't trust a nightlite to carry that load. Why don't they just use one quality power wire and one quality ground? Why complicate things?
