This issue is really puzzling me. I'm trying to get a mostly new setup going, I've been strictly complying with the user guides and I'm reasonably sure everything has been set up the way it should be. The motherboard is a brand new Asus Prime Z270-AR housing an equally new i7-6700K CPU. I took the PSU, a Corsair CX750w, from my current PC, as well as a GTX 760 (temporarily) and a Seagate 1TB hard drive into the new build. Problem is, I can't get the thing to power up under normal means. Power LED lights up as soon as it's plugged, but neither pressing the power button or the motherboard's own power switch does anything, no boot, POST or spinning fans. We were able to get a seemingly normal boot by shorting the green wire in the 24-pin connector, indicating that the usual methods are just not getting the PSU to supply the system. Should I suspect a motherboard defect? I've heard of motherboards refusing to power up in order to prevent electrical damage but its user guide only mentions the jumpers and connectors should be checked again. What else should I be looking for?
