    Only other reason they blow apart from faulty is power feed related problems - Meaning power Surges.

    Yeah, something a lot of people don't think about is that the supply of power to NZ homes can be inconsistent and "noisy". Erratic and sudden dips and surges in the feed can lead to all kinds of issues. This is especially true if your wiring has seen some mileage.

    We re-wired our house in Auckland (new wiring and switchboard) and even after that the lines were "noisy" I ran a passive line conditioner on the circuits where my PC/Network gear was plugged into and it made a huge difference... EMI/EMR (which I could hear as coil whine over my speakers/headphones) went away...

    The power grid is noisy in any country, that's why devices often include protection against the usual transients etc.

    To make the power supply blow up would take a bigger than usual surge, such as from lightning nearby, and in any cause would likely have damaged something else too.

    If your house wiring causes that much grief you should be calling an electrician ASAP, and probably, the fire department...

    There could be many sources for such interference, potentially even some cheap/faulty item of your own equipment.
    Non-system disk or disk error. Replace and strike any key when ready.

    bottom line is PC Power Supplies fail.
    PC PSU's were one of the most common points of PC hardware failure (after HD's)

    Even new PSU's can fail. Some have a terrible failure rate ( Ive known of 30% fail rate from one seller , and a 100% fail rate over 3 years from another )
    They fail. Its not uncommon.

    Chances are it wont be issues with your mains power that caused it, unless everything else in the house also failed at the same time
    Ive known of a huge spike that blew everything in the house EXCEPT the pc
