Overload Tests
Hardware Secrets Golden Award

Before overloading power supplies we always test first if the over current protection (OCP) circuit is active and at what level it is configured.



As mentioned, we discovered that OCP was set at 25 A as we couldn’t pull more than that from +12V2.

Since we were already pulling the maximum we could using our equipment (33 A from its +12V1 input and 25 A from its +12V2 input), the only option for us to overload this power supply was to increase current at +5 V and +3.3 V.

The idea behind of overload tests is to see if the power supply will burn/explode and see if the protections from the power supply are working correctly. This power supply didn’t burn and when we tried to pull far more than it could deliver it would shut down, so this unit passed on this test.
