    Engineers can be a little caustic at times; it takes a little getting used to.

    I imagine you have had your own frustrations with people thinking they know how to cure an ailment.

    How much does electricity cost on Christmas Island? I imagine it is diesel powered.

    I assume the computer could sleep; I would expect a power supply to last a lot longer than 5 years under such conditions.

    Absolutely… if a short pulls 62 amps and so does not trigger shutdown, that is a LOT of heat.

    Electrolytic capacitors can age faster when not used than when in use.

    Interesting, I also have a supply whose fan is controlled by the PC mother board.

    I'm not sure I even have a power supply that isn't at least 10 years old!

    While I tend to agree, I would test the RAM with MemTest first.

    Most modern supplies can handle around 90-264V, and you are running 220V, so I doubt voltage sag is to blame.

    Stop over-clocking and see how that helps.

    There are 12, 5 and 3.3V outputs, if only one is regulated (group regulation) then when the supply is loaded it adjusts to keep that one voltage the same, and then others can be affected. If the...

    Good to know, thanks.

    but what do you mean by "that doesn't take load into consideration"

    This link suggests a possible grounding issue, so that would be the first thing to check.

    Assuming only capacity is increased (and quality not decreased) then life and reliability may be increase by over-rating; efficiency may also improve and with it the fan noise may be less.

    One nice feature might be an LED on the power supply that flashes when one approaches over-current on one of the rails; would help with balancing.

    Absolutely, that is where I like the D-Link emergency room; if one 'bricks' the unit, turn it on with the reset button held till the power light starts flashing to access the recovery page.

    firmware

    With power supplies moving digital, is it getting to the point where one might be able to upgrade their firmware?

    It is almost always capacitors when the power supply of a monitor goes, so if you are handy with a soldering iron you can repair it and have a unit that will probably last longer than before if you...

    Imagine very low frequency ripple, the smoothing capacitor can not keep the voltage steady over such a long time; the higher the frequency of the ripple the easier it is to eliminate.

    Almost certainly more damaged than what is seen, so not worth repairing.
