Overload Tests

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

We configured our load tester to pull 33 A from the power supply +12V2 rail. The unit didn’t shut down, meaning that either over current protection (OCP) was disabled or configured at a value above that.

We always try to overload power supplies maintaining them working inside ATX specs. Since ES-800 was already working out of the proper range when delivering 800 W, we decided not to overload it.
