I've run into a pretty bizarre situation and am not sure what to make of it, so hopefully, someone here can help:
My friend's computer isn't powering on. I troubleshooted it, using my computer to help. His motherboard wasn't getting power (checked using the motherboard USB ports). I made sure everything was plugged in correctly, and it appeared to be, so I then plugged his motherboard into my power supply, and the motherboard became powered. After checking with the original power supply one last time (still didn't work), I recommended a replacement power supply as I was sure that was the issue. However, the new power supply also does not power the motherboard, and after some additional experimentation, we discovered something quite interesting:
What could we be missing? We're honestly pretty stumped. (It's not the outlet or the power cables, we checked those; and we are using each power supply's respective motherboard cable, not mixing and matching)

- His original power supply powers my motherboard, but not his
- His new power supply powers my motherboard, but not his
- My power supply powers both motherboards
