    We received a system back from one of our client. The report said there was smoke coming out of the system along with a burning plastic-like smell. This is what we found.

    I've seen several hundreds of PC's over the years. Never ever saw anything like this. Dozens of PSU's dying but that's about it. Tons of grime and dust, but never this.

    Fire's in PC's have to be extremely rare.

    I'm guessing a manufactures defect caused this small electrical fire. Good thing there wasn't an accelerant / combustible fumes near this PC when this happened. I do have a handful of PC's being used near CNC machines and other types of machinery.

    If the client wants the data saved it might be possible to source another exact drive and swap out that mainboard as long as there isn't any hardware encryption. maybe. I've never disassembled a hard drive before.

    it holds surveillance video. The customer already informed us that no video was needed.

    I take it was a bad PSU connector.
    I heard/seen from other people that the pins on the SATA PSU con touch.
    I kind of miss the good old 4 pin molex days, minus the floppy style.

    There were some cheap SATA power splitters that had this defect. Thankfully I have never had this happen to me.

    Same here, had a multi HHD swap bay which I used a lot, hated to see one of my drives get toasted.

    I have another case of a meltdown which happened about 5 - 6 years ago. It was another surveillance system. Once I find the pics, I'll make the post in the motherboard forum since this involves a PCIe slot.

    Yeah, that was a SATA plug issue, not a HD issue IMO.

    Reminds me of plugging in AT power supply cables backwards.

    I’ve seen it happen on Molex a few times. Generally it’s not that the pins touch, it’s that the crimp from the wire to the pin is poor, which creates a high resistance connection that leads to all the heat. Then it’s a race between the cheap PVC insulation on the wire and the cheap plastic on the connector as to which ignites first.

    Lol, the good old days of the teacher telling us to triple check the PSU connectors and jumpers.

    Wasn't the rule to connect it so that the black wires were adjacent?

    TBO, I don't even remember, 96 was the only time I touch AT PSUs.

    I still have one in my attic. I have used it from time to time in electronics projects that need a 12V or 5V supply (that is before I replaced it with a proper supply).
