    Do you have a voltmeter? if so you could check the voltages to see if they are what they should be before plugging it in.

    The warranty option is not a route you would consider?

    I know this is not what you asked, but seems a possible solution to your situation.


    P.S. I'm also a Brit.

    I don't think coil whine means it is going to fail, so if you can live with it, stick with it.

    If your socket meter reads 466W and the efficiency is say 90% around full load, then it is actually only delivering
    420W, so there is already some headroom built in by ignoring this.

    Those decoupling/bypass capacitors are already on the mother board (closer to where they are needed) and so are not necessary in the cable; another problem is that large capacitors have significant...

    It is the mother board that varies the load, not the power supply, so that is where the capacitors should be.

    My point was just that a 10 year warranty may not mean there is a good chance it can last 10 years (24/7) at full load, just that you can get a replacement.

    If you are running a server, get a...

    Just for the sake of argument, not to be offensive, I doubt many high quality supplies can last 10 years (24/7) at full load. The warranty is a statistical gamble that few people will run 24/7, after...

    Normal 105C electrolytic capacitors might last 3000 hrs at 105C; now life doubles for about every 10C cooler, so lets run them at 45C, which is 6 doublings

    3000 x 2^6 hrs = 22 years
