Hello there, I made a very costly error and accept I am an idiot for doing so. I should have disconnected the power before trying to do anything with my custom power switch/cables. I'm just trying to gauge the extent of the damage and would appreciate any guidance in diagnosing as much of the damage before replacing parts or bringing it to be repaired.
So I just had POWER + to POWER - through a momentary NO switch.
12V over SATA direct from PSU (Corsair RM850x).
Upon adding another switch for a separate unit to my external panel, the pc power switch was in the way. In undoing the terminals, I presume (didn't see it) I touched the 12V line to the 5V line because the PC booted but then died. I cut the power within 5 seconds as I knew I effed up.
Troubleshooting:
Reconnected the cables to my case's power button as normal.
Upon first retry, the PC didn't boot. No lights on MOBO (gigabyte Z390UD), no beeps but I cut the power quick because I could hear something rising, as in, a seemingly increasing power consumption. Reconfirmed all cables etc were in correctly. Tried again, no luck.
No burning smells.
Inspected motherboard and parts and there doesn't appear to be any discolouring, misalignment or any visual problems.
I visually inspected the PSU from outside the casing and there doesn't appear to be any discoloured components, caps or fuses etc with damage appearance.
Following that, I disconnected all power cables from the PSU, leaving just the 24 pin ATX. I jumped pin 4 & 5 and the PSU fan spins. PSU seems good.
I don't want to reconnect the MOBO for fear of doing more damage. I'm praying I didn't fry multiple components!
If anyone thinks I should just go straight to the repair shop then I'm happy to do that. I have a multimeter so I'm willing to try a bit of further diagnosis but I have no experience in doing so. That being said, I did build the PC myself and I don't feel nervous handling computer parts if that makes any difference.
Thanks for taking the time to read my issue
