Dear technicians,
I have got an old Asus ATX motherboard and an old ATX PSU.
I used the PSU with other motherboards and it worked fine.
then, I connected the PSU to the mentioned Asus motherboard. then the motherboard turned on but I smelled burning plastics from my PSU. and the PSU failed.
After that, when I connect the PSU to other healthy motherboards, it does not work.
I measured the ATX power pins on the mentioned Asus motherboard. no pin was shorted to ground. offcourse, there might be some short on other parts of the Asus motherboard. but not on the power pins.
Now I have a question.
How can an ATX motherboard without short on its power socket, burn the PSU?
