Morning all. Its been a long day. Started my first build today to find it looks like I have no power on my MB. I can press the power button and fans kick in but nothing from the MB. I removed everything and tried a bios update following the instructions from the Asus Website. However its doesn't seem to want to run from the USB. I checked the wiring loom from the PSU to the MB to find a cable was connected PSU end, but the cable was missing from the MB. It looks like its never been terminated, there just isn't a cable there. Do you think this is the problem or is it something else? The cable that is missing is pin 20.
