Yes. Remembering also that even a good power supply running too long on a below-normal voltage source can be damaged by that over time.

Also keep in mind the mortal enemy of all computers and electronics: heat. Over time, that bakes the life out of electronic components like capacitors and power supplies.

Plus inserting and removing connections (such as PS cables, drive cables, etc) and changing components (such as cards and memory) can fatigue circuit boards around those points, eventually leading to failures.

I personally am always angry when electronics die. They're supposed to last forever! ;)

For dying computer owners: before upgrading anything, use a known good PSU. I just lost a week worth of late nights trying to set up a new computer. I deducted that it was the PSU on the nearly functional computer that had caused CPU failure, by having something else than DC voltage. On the average the voltages were a bit low, but contained AC spiking.

That CPU didn't work with decent PSU (normal voltage levels) anymore, on any board I tried - the other boards didn't even boot into BIOS. I had three PSUs to test and always it was the old one that made the old board work so well that I could install Ubuntu Studio and upgrade it even once, but then I got jams and interrupted HDD writes.

I postponed indefinitely testing the other boards with another CPU because I had an older computer that had no problems - and still runs fine.

PSUs are dangerous! :)

    My main desktop/server, also rather old, finally died. The onboard
    went first. Then the machine just quit coming up at all.

    The backup desktop/server still works. It's "newer" than the dead main
    one, but has some peculiarities. For example, the BIOS doesn't
    the presence of a keyboard unless it's plugged into the PS/2 port. Once
    Linux comes up, it works just fine with my USB keyboard, so it's not a
    problem with the keyboard.

    Hoping to replace the guts with a Ryzen 7 motherboard. Could use the
    speed for other things I do.

    Well, in my experience, upgrading from Ubuntu 16 to Kubuntu 18 was a
    hairy problem. For instance, after upgrade and restart, no working
    network. I reinstalled fresh.

    In my experience, only if you want to keep Windows around.

    Well, putting Linux on my wife's retail laptop PC that came with
    on it worked just fine. Dell, Lenovo, HP apparently work. Only
    ointment-infestation I can imagine might be support for fancy new
    graphics cards?

    At the moment, I like Asus motherboards. My wife's laptop and the mobo
    in my backup desktop machine just work with Linux.

    Since my present laptop experiences a few issues (doesn't think it
    has a
    battery, takes 3-5 minutes before the built-in display shows the POST
    screen) due to having been dropped a few times, I'm thinking of jumping
    to a Dell 15"/4K HDR display and Intel processor.

    Looking for hardware that won't leave me crawling when I move to a
    42mpixel camera and get to start making big panoramas.
