    Is this test performed with all the devices attached, or it it performed on the bench with suitable sources?

    lol, could you be a bit more specific?

    A PSU is rated for its output. It is only guaranteed to produce that at the rated load and if you are lucky it also has specs for minimum load.

    For practical reasons you might even ignore both of those max/min load specs and instead test at the needed load for whatever you're powering, yet that is a gray area, it should perform to specs, and yet, much of the Chinese junk doesn't so you could be more interested in fit for purpose rather than meets specs.
