Antec VP450 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 passed this test, as we couldn’t pull more than shown in the table below, as the power supply would shut down, showing that its protections are present and working fine. During this extreme configuration, noise and ripple levels and voltages were still inside the proper limits.
