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.



Here we were limited by our load tester, which can pull “only” up to 33 A from each one of its +12 V inputs. Pulling 33 A from each input wouldn’t shut the power supply down, which makes sense, as the label says that each rail has a 38 A limit (not forgetting that usually manufacturers configure OCP at a level above from what is written on the label).

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 or explode.

Below you can see the maximum we could pull from this power supply with it still working within specs. Even under this overloading efficiency was above 80%.
