That sounds more plausible than the power brick knowing about the
temperature of the computer. You can probably check if the power
rating of the brick matches the power consumption of the computer (it
came with it?)
Yes - it came with it. To make it worse - the manufacturer replaced it
and the second machine (new machine, new power brick showed the same
issue)

11.8 Amps at 19.5 Volts calculates to 230.1 Watts. The power supply is
230 Watts. Unless the .1 Watts is significant or there is an error of
some kind then they are extremely close.
A recent computer with a recent kernel should never get to the point
where the CPU turns off because of high temperature, it should
throttle much earlier. If that is not the case, you may check if
automatic throttling is not disabled somewhere.
It is Ubuntu 20.04 derivative - fully updated, and the bios is also
fully updated. Both CPU and GPU are not overloaded in terms - they
never lock at 99% on all cores (my old machine can run on this load
for many hours - no overheating - max goes to about 90 Celsius no
power supply disconnect). But the new machine runs often at more than
100 Celsius (as a peak temperature). Normally it is within 85-95 under
load but peaks above 100
What are the peak temperatures of your computers when under load?
I do not have an AMD laptop but I have heard of this issue before. There
are several Youtube videos discussing solutions. Have a look at this one
to see if it helps:
