OCZ ZX Series 850 W Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. If we tried to pull more the unit would shut down, showing that its protections are working fine. During this extreme condition, however, noise and ripple levels at the +12 V outputs were above the maximum allowed, at 175 mV, and voltages on the +12 V outputs were below the minimum allowed, at +11.23 V (the minimum allowed is +11.40 V).
