High Power Direct12 BR 850 W 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 were working well. During this test, all voltages were still inside the tighter 3% regulation, except the +3.3 V output, which was way below the minimum allowed, at +3.02 V. Ripple and noise levels were still very low, except at the -12 V output, at 104.5 mV (still below the maximum allowed).
