Hello Tony,
The power bricks draw very little current with no load
on the output and 2.5A
would be fine to power one up.
Are you saying that I can test them with no load? I thought they would need some load?
Most, if not all, of the power bricks start by rectifying and smoothing the AC
input. As a result they will run off a DC input too.
You can test them using a bench supply, normally do.
One final thing. Do not, (as I did when younger and even more foolish)
disable the over-current trip in a power brick. If the crowbar operates, you
will end up with transistors blown off the PCB.
