To make things worse, most European power companies provide a wall
voltage of 220V, not 110 as is common in the US.

Hi Bill,
Don't confuse WATTS with AMPS. You see, power is measured in watts and is
the product of voltage * amps, so a 10 WATT supply can produce either
10volts at 1 AMP or 1 Volt at 10 AMPS and still be a 10 WATT supply. The
PC supplies are typically 250 watts. When they supply 5V at 25AMPS that is
using only 125 WATTS. Your wall plug can supply 110Volts at 15AMPs which
is 1650 WATTS. (however running a house wall plug at 15Amps for any length
of time will warm it up, and generally several wall plugs are on a single
20A circuit (2200 Watts max))

How can a normal PC XT power supply deliver
25-30A, when its plugged
into a normal 15A wall socket? Or is the amperage way different in
the UK?
