Ok, at this point, I'm thinking that it is because I am using an ATX PSU on a non-ATX board? So it's not getting the signal to turn on. However, the baord advertises itself as an ATX board for some reason. But the power switch wire is connected to J6 on the M1, so it should still get signal to turn on? Or is that just for sending on and off signal to the motherboard? But what turns the M1 on if the motherboard is off? I'm confused.
The motherboard manual says CN4 is the ATX power, however it looks like a jumper? Do I need to splice the ATX connector in there somehow?
