A single output 5v smps? A "guesstimate" would be to multiply the input
power by 0.6. If the input was 2a @ 115vac, the 5v output current would
be *in the ballpark* of [(2 x 115) x 0.6] / 5 or *about* 27 amps DC.

The rated input current *should* be on the PSU label.


Just load it with an automotive taillamp and measure the voltage, that
should be adequate for the PSU to regulate, you don't have to apply max load
for the initial test.

What is the intended load?
