I removed the â€œGOLDâ€ psu from the case, and gave a visual check inside through fan grill. I noticed the coil burned (the one with many copper wires). What it is amazing is that in the middle of the coil there is a plastic cable tie tightens the coil, I think. IT THIS SAFE?
Also the plastic foil has many dots of burn on it. It helped do not fall into the caseâ€¦motherboard and other components.
The failure probably did not occur there. It probably occurred somewhere on the PSU's primary side. Something probably failed shorted, causing a short circuit, causing a great deal of current to pass through the primary circuit. Past that... I don't know.
Corsair will want to do failure analysis on your PSU.
