I need to convert an ATX power supply to be on any time the main switch on the back of it is turned on. It is going to be used to power a passive backplane that has an ATX connector. The backplane will not have an SBC computer card, so I can't go the regular route. Is it safe to just short pin 14 to a ground with a jumper and leave the power supply on all the time that way? The board will have several PCI cards in it that will be drawing 5V power, so a load will always be present, but I don't want to hurt the board or the cards if the shorting trick is a no-no for bringing power to the board rather than just testing the PSU. Thanks for any help.
