    Saw this today, a customer brought in their pc which had literally caught fire. The vents on the psu were all black and burned, and the inside of the case was all scorched at the top. Needless to say, it had that horrible horrible stench.
    Surprisingly though, the whole PC worked fine after a new power supply!
    The pics say it all.

    WTF? Someone bought a PC in to fix, what's that got to do with how good his shop is.

    Yeah exactly....

    Maybe 'Slowbart' as your location suggests Dalien, is quite appropriate.

    :rolleyes:

    +1 for the never buy cheap power supplies,
    Few years ago i had one and somedays the computer would refuse to boo because the video card wasn't receiving enough power!
    Also replaced many in friends machines, absolute shit quality!
    Needless to say i have a high quality enermax powering the system now :p

    Yeah this was on the very cheap end of the scale, 'Mirage' was the brand. Typical galvanised casing, '500w' apparently.

    Worse than the average cheapy you get with coolermaster or aopen cases or similar

    EDIT: to clarify, not bagging out coolermaster or aopen, was merely a comparison to explain how much of a cheap unit this 'mirage' was :D

    Can't see anything at all in those pics.

    I agree with you though - I run a server which is way underpowered, all the programs randomly crash. Nothing I can do though, can't afford a good one for it at the moment. :(

    Yeah just realised how badly those photos suck, they dont look as bad on the phone. Will re-take tomorrow.

    Basically, the 240v side of the PSU is completely burned, all capacitors exploded, 2 were stuck to the top of the case! All the components were melted right off the board, the whole thing was obviously burning for a while.

    He should go buy a lotto ticket. I'd expect it to blow everything else up as well. If I was fixing it I would replace the whole PC. Wouldn't trust the MB or HD after that

    Yeah hdd got a full backup after that.
    PC was a piece of junk anyway so they weren't concerned about it, only worried about the data.

    That's an understatement!! AOpen and Coolermaster are way above the no-names. A whole other category of PSU.

    Doesn't surprise me that an el-cheapo would burst into flames. Would only take a small buildup of dust and a popped cap overheating. 2 things extremely common in a no-name PSU.

    Yeah I know, that was just in response to the poster who was concerned about his coolermaster psu :)

    Even though I have good quality PSUs, certainly makes me think twice about leaving my PC running when I'm not home!

    I've had a computer catch fire on me once. Was in my more dodgy days, when I used wire that wasn't quite beefy enough, it heated up and the cheap electrical tape around it caught fire. Thankfully I was sitting in front of it when it happened and so turned it off straight away.
