Seventeam ST-650PWL Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. We couldn’t pull more than that because the power supply shut down, showing that its protections are working just fine. During this test the noise and ripple levels at +5VSB were above the maximum allowed, at 61.2 mV, and the noise and ripple levels at +3.3 V were touching the limit, at 48.6 mV. The voltage at +5 V output was below the minimum allowed, at +4.71 V.
