Enermax PRO87+ 500 W Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. If we tried to increase one amp at any given output, the unit would shut down, showing that one of its protections kicked in, which is always the desired behavior. During this test, the noise level at -12 V output was a little bit above the maximum allowed (122.4 mV), but noise levels at all other outputs were still very low, and all voltages (except -12 V) was still inside a tighter 3% voltage regulation.
