PC Power & Cooling Silencer Mk II 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 at 146.6 mV, surpassing the maximum allowed (120 mV). All voltages were still within 3% of their nominal values. It is interesting to note that the manufacturer labels this unit as having 600 W peak power.
