NZXT HALE82 850 W Power Supply Review
Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. Pulling more than 31 A from each +12 V input from our load tester (i.e., more than 62 A) caused the unit to shut down. Since this was the configuration we used during our 850 W test, we could only increase current on the +5 V and +3.3 V rails. If we tried to pull more than what is described in the table below, the power supply shut down, showing that protections were in place. During this test, ripple and noise levels were still extremely low; however, the +5 V, +3.3 V, and +5VSB outputs were outside the tighter three percent regulation, at +4.84 V, +3.10 V, and +4.84 V, respectively. Under this extreme test, the +3.3 V output was below the minimum allowed (+3.135 V).
