How to determine if you damaged your PSU
I accidentally connected a 6-pin adapter to my PSU while the computer was off, but I noticed it wasn’t the right one and unplugged it. The power supply stayed on, yet the PC didn’t turn on until I removed the adapter. After leaving and returning a few hours later, I discovered the circuit breaker had tripped. I restored it and the PC booted up successfully. Even though I’ve had problems before, I still have some issues that I’ll discuss in another post.
How can I determine if this PSU caused the damage? My system has been running for a few weeks now, but I’m experiencing Kernel 41 problems and screen flickering—less severe than replacing the motherboard. I don’t expect to see any internal components visibly damaged. Could a PSU tester from Amazon provide useful information? I’d appreciate guidance if I have a multimeter and know what to check. Thanks!
How to determine if you damaged your PSU
You obtain another PSU from a different source and run a full system test to confirm the problem remains.
Another important step is ensuring all connectors are correctly connected with the appropriate harnesses. Standard testers that only connect the green and black wires on the 24-pin connector are ineffective. You should use something like a Passmark PSU tester, but it would be expensive to purchase multiple high-end units.
That's what I was worried about, yet it was precisely what I required to understand. I still have another one nearby, though I'll need to confirm whether I possess all the cables.
Are the random PSUs you possess secure for your project? Which computer are we talking about and what were the specific units? Unless you're operating a very simple workstation, finding an adapter is usually a major warning sign; anything that can handle multiple connections should be reliable enough.
5800X3D, MSI B550 Tomahawk, Asrock Taichi 6800XT, Thermaltake Grand 850W. Changed to M.2 only; my RGB now uses SATA power and I don’t want a long cable for that. The extra PSU is a Seasonic 750W Gold, but I might not have enough GPU power cables for it. I’m checking if I have sufficient cables for the spare, and if not, I’ll try borrowing one. That’s a helpful tip, thanks!
I changed to a different PSU but the problem continues, so it seems okay
