TLDR;
PSU not powering up any of my PCs. Paperclip test does power on the PSU. Stopped working after a power loss.
Ok, weird issue:
System has been running fine for about 8 days (Fresh build all new components)
System was kept on last night doing some housekeeping.
Before I woke up, someone turned of the power at the circuit breaker to change a outlet somewhere else in the house.
Naturally - the PC was then off once I woke up (power outrage - no surges or what not, just basically unplugging PC while it's on)
(Another PC - also on over night was off but could turn it on normally - no problem there)
So when I woke up, tried turning on the PC - annnnnd No go.
No fan spin up nor any RGB .
I thoughts it's weird maybe the outlet is not working?
But - I did the lamp test and there's power and all is well.
So PSU just doesn't turn on when pressing power button. (The Mobo doesn't have a standby light)
Installed PSU into an older PC/mobo
Great - the standby light is on - so there is power coming through the PSU.
But now... when I press the power button on this older PC, still no turning on or anything (It's like I didn't even press the power button)
Took the old pc's PSU and installed it in the new rig - powers on just fine, post nice, bios says all is swell. - So new PC/Mobo is not the issue.
So problem is definitely on the PSU, right?
Ok so I jumper the PSU - maybe it isn't getting the turn on signal.
Jumper the PWR_ON and COM pin:
And the PSU turns on. Its fans spin up and the voltages are all good. 3.3, 5 and 12 on all the necessary pins.
I though OK, weird, maybe it is now.... "reset".
Reinstalled in my new rig, tried powering on - NADA.
Last attempt - installed in old pc rig. still nada.
What is happening - Why can I start the PSU with the age old PSU test (Paperclip test)
but it doesn't want to start up any PC?
Thoughts anyone?
(I sent it back to supplier - as it's almost out of return window.) - awaiting their feedback.
PSU: Fractal Ion+ 750w
Mobo: B450 Gaming Carbon pro AC.
Outlet: 220 V
Confusion: MAX
