Yesterday I was upgrading my PC's CPU to a Ryzen 7 5800x, and I noticed a loose cable. I was tired and put the cable in the fan header, which was just barely long enough to fit in. With my half-sleeping head I didn't notice it was the floppy cable and when I put my PC on the port was smoking and glowing. When I realized it was burning, I put the I/O switch on the PSU off. I pulled it out and tried to put it on again, but it was smoking again. Damn, I've just fried my motherboard, I thought. It didn't turn off both times, and if it didn't smoke or so I would have thought it would have started normally. It's especially stupid because I've assembled a few PCs before and I am fully aware it is floppy cables shouldn't go there (or anywhere). I accepted that I should buy a new mobo, but I wonder if it did any damage to other components.
After the incident, I've disassembled everything and did a close inspection of the board. It only seems the fan header is burnt, and the heat discolored the eight-pin connector's edge. For the rest everything on the MOBO seems normal, I tested my SSD on my laptop which works fine, I've tested my PSU with a cheap AliExpress tester which gave the following results: 12.0 -12V, 11.9 +12V2, 4.9 5VSB, PG 300ms, 4.9 +5V, 11.9 +12V1, 3.2 +3.3V. The LEDs on the left didn't turn on as expected, the +12V led only turned on with the molex inserted and the +3.3V and +5V only with the SATA. Again, it's a cheap AliExpress thing so I doubt it's reliability. The other components aren't elaborately tested except to see if there's physical damage. There isn't physical damage. Probably I should go to a neurologist to see if I've got brain damage.
Do you guys have any input whether if components could be damaged as well, or is it just my mobo? Thanks in advance!
Specs for my mobo and psu:
Corsair RM650x (brought it in 2017)
Gigabyte x570 aorus elite
