be quiet! Dark Power Pro 10 850 W Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. The objective of this test is to see if the power supply has its protection circuits working properly. This unit failed this test, since it burned while it was configured as described in the table below. This may mean that we got a defective sample, so we asked a second sample from the manufacturer, which should arrive shortly. So, do not hold this result against the manufacturer before we do test the second sample. During this test, noise and ripple levels increased a lot, showing that the unit was reaching its limits (85.6 mV at +12VA, 90.4 mV at +12VB, 30.2 mV at +5 V, and 46.0 mV at +3.3 V). All voltages were within 3% of their nominal values.
