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! ;)

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
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
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.
