Would you have to connect the 24-pin green Power-on wire to a ground, so the PS was always on, as there is no sense/load delivery from a 2 or 4-pin power delivery to CPU MB molex on thin iTX boards, ie a connection without a sense signal will not turn on the power supply when the power button is pushed?? This assumes the board will run on 12v, as most require 19v. (Further research states the 5v sense must be connected to a 5v at the ATX 24 pin) (Adding a switch to the green power on to ground will give control) RepRap
