Hi. Just a quick question which is kind of off topic - with switched power
supplies like those in modern PCs, when it says the input current is 7 amps at
115 volts, is that the constant no matter how much the computer itself draws,
or the maximum, no matter what? If it's the latter my computer room is
No, it's the maximum current that the supply could draw if all the
outputs (probably including the mains output to the monitor) are fully
loaded.
With less load, the input current will also be a lot less.
