    Hi , thanks for sharing . I have been using my atx power supply as an bench power supply to power my embedded projects.. Today when I used it once after I turned it off and turned it back on after a while.. The only standby light is working.. And its not responding to PS_ON as that pin is shorted to ground through a switch..
    What can possibly go wrong with it suddenly ? .. No swollen caps and no burnt fuse.. Its just not responding to the PSOn any ways yo troubleshoot it ?

    Thanks in advance
