Cross Load Tests

For the generation of the following charts, we set our loaders to auto mode through our custom-made software before trying over a thousand possible load combinations with the +12V, 5V, and 3.3V rails. The voltage regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. We should note here that we only run this test with PSUs that have a capacity equal to or lower than 1000 W. This test takes a long time to run since the capacity of a unit increases the completion time of a cross-loads test exponentially.
