Re: Crack & Stink Gigabyte GA7N400 Pro 2
Unlikely it happened that way around as most PC PSUs just shut down when their output is shorted, so the only way to kill a PSU with a shorted motherboard is if the PSU itself is a totally trash design that has no short circuit protection - which would be a PSU not worth using in the first place, and its death would be of little importance...
(Note, I am ONLY talking about PC\ATX PSUs here, MANY other PSUs (including SMPS and linear) do NOT have short-circuit protection and shutdown)
The fact you already have bad capacitors shows it's most likely the PSU that went bad first. momaka already explained the most logical scenario in post #34.
The bad capacitors in your PSU caused instability and\or other improper operation and likely resulted in the resistor burning out in the PSU.
Failure of the PSU likely led to the incorrect voltage going to the motherboard on one or more rails, which killed it.
