Not sure where to ask for help so here goes.
I have two desktop ATX PSU which won't turn on the PC. One was the original and the other is a replacement. Both light the standby power light on MB when installed but won't start the machine when 'ON' button pushed.
I checked all the connectors while manually turning the supply on using jumper and every voltage was in spec. I added hard drives and rechecked and still all voltages in spec. I am wondering if the circuit that says power is ok comes from the MB and maybe it's the culprit? Is there a test for the power OK that can be done with a DMM?
I took another PSU, connected everything and the machine runs fine but the input receptacle/switch is wrong location for opening.
I'm leary of buying another replacement but I would like to put the case back together
