Overload Tests
Hardware Secrets Golden Award

If we tried to pull more than 52 A from the single +12 V rail this power supply would shut down, showing that over current protection (OCP) was present and active. Below you can see the maximum we could pull from this power supply with it still working within specs. If we tried to pull more than that the unit would shut down, showing that one of the power supply protections entered in action.
