Unless you have a very crappy power supply, 5% should be well within the
tolerances on input voltage.  Many power supplies will run anything
bwtween 100 and 250V as input and adjust automatically to generate the
correct output voltages.

Maybe years ago we had power supplies that would only run at 110 to 115V
or something, but I doubt that is the case with any modern power supply.

So looking just a little, something like an Antec TruePower 480 seems to
say it runs either 115 or 230V, although I am sure it has some
tolerance.  Meanwhile a PC Power and Colling TurboCool 510 has the input
range of 90 to 264V automatic with supposedly a .99 power factor.
