[wellylug] OT: 4.6V on the 5V rail is indicative of....?

In my experience power supplies are pretty tolerant of mains input level (my
own house varies between 210 and 255 as measured with a Fluke power monitor,
but the kids PCs keep running (MY pcs, the important ones, live behind a UPS
;-) )
The power level can only be one of two things, either the PSU is failing to
deliver, or something in the PC is pulling the voltage down.
What is the claimed wattage of the PC, how many devices in the PCs leeching
off it?

Hi,

Apologies if this is too off-topic.  If a motherboard is indicating it
is getting only 4.6V instead of 5V, is this generally caused by the
power supply unit failing to deliver the needed power?  And if so, is
that something that occasionally happens to a PSU, or should I be
looking into the quality of the power coming out of the wall power
socket (it's  a 1930s house)?  It sure makes the PC unstable!

Thanks :)

Damon
