I have a ups
and when the wall voltage get below 210 V
my UPS rise the voltage to 243V
then my UPS bring it to normal when the wall voltage rise from 211 and up

it happened randomly
can that damage the psu or the pc ?

Hi
Unless that is a very cheap and poor PSU then that voltage will not affect your equipment,most PSUs will operate quite happily up to 250 Volts.

It is wirerd that the UPS [(Uninteruptd Power Supply)] raised the voltage from a normal AC wall current passing through it above the normal voltage
normaly a UPS will regulate the current to a constant voltage even if the AC wall current is above or below the normal in your region
however if this happened one time at random
there should be nothing to worry about
but still I'm not sure

You may have a UPS that are designed to work on 230V(try using a true RMS multimeter to measure), and I guess your standard wall voltage is 220v? So it will turn into low-voltage protection mode too early, what the exact model of your UPS? Maybe you can adjust the threshold.

In the UK the Electricity Board by law must deliver 230 volts +10% - 6% (ie. between 216.2 volts and 253 volts), and to maintain the frequency at 50Hz ± 1% (ie. between 49Hz and 51Hz) over a 24 hour period

Previously the UK was 240V but they the EU forced us to change. To 230v . Actally we didnt do a dam thing - now we were goung to swap billions £ of transformers for some bureacrat. So we just widened the standard.
You got a UK PSU thats all . Doing its job

Actually it wasn't some bureaucrat but because we started to import electricity from France through the channel tunnel link and our standards needed to match theirs.
However you are right that we didn't change anything but just widened the standards.
