Hello I'm writing here because I have absolutely no knowledge on how PSU works and I need help. What happened is that last night when I turned off the pc I connected my phone to the cable which was connected to the mobo in order to recharge it. It usually works. But this time when I connected my phone, my pc turned on or so I thought but it was weird since it was too silent and it didn't beep. I ignored it, turned off the psu ( from I to O) and went to sleep. In the morning I couldn't turn on my pc so I guessed it was psu problem and it of course was. I could turn pc with other psu and couldn't turn on other rig with my tagan. I think that what happened in the night is that when I connected my phone, the only thing that turned on was psu, without powering mobo and rest of the rig, but I honestly have no idea how it could happen. Now when I change the switch on the Tagan from 0 to I I can hear something there clicking but in no way can I turn on the pc. So my question is: Is there a chance for this psu to come back to life or there was some kind of short circuit when I connected my mobile phone and I should forget about it? Kind regards!
