Overload Tests
Hardware Secrets Golden Award

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