I suspect you have a low-power computer by today's standards. They may
not use the 250 W or 400 W indicated by the power supply (a number that
is both "theoretical" in that it can only be obtained under certain
circumstances, and fictional in that they're usually built to price, not
build quality, and the manufacturers know they're unlikely to be found
out), but thopse figures aren't always that far out.
A modern Pentium 4 CPU, on its own, will often take more than your 60 W,
and the PSUs are rarely that efficient. And of course, there are drives,
up to four or five fans, and the rest of the PC to consider.
All this only serves to illustrate your real point, of course: modern
PCs are not normally low-power devices.

servers are PC based, and we're not in a part of the world where air-
conditioning is normally needed).
