    Well, the thermal pad caused the diode to fail. It's not like a failed thermal pad alone is going to cause the PSU to cease working. But a failed diode will. :-D

    It seems a little unfair to me to say that the power supply failed because of the diode.

    Well, it's more like a chain reaction: thermal pad fails, then diode starts touching somewhere caused by poor insulation, then diode fails and an electrical reaction happens. PSU dead. Dead by failed diode. Betrayed by the thermal pad. What a gossip!

    If the fuel runs out in a plane does one blame the engine for failing to run?

    Anyhow, it is good to know what the problem is.

    No. You blame the pilot.

    I hope this is not like admitting that is you guys at Corsair's fault!

    Sounds like a manufacturing issue, where the thermal pad was the sort used for a CPU and not a high voltage component.

    I wonder what Corsair specified on their bill of materials

    BOM was correct.

    I'll wait till this blows over before I reveal where the mistake was made.
