Cross-Load Tests And Infrared Images
Our cross-load tests are described in detailĀ here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 1500 possible load combinations with the +12V, 5V and 3.3V rails. The load 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.

Efficiency Chart
As you can see in the graph above, efficiency is quite high. The sweet spot is between 100W and 475W, with up to around 95W combined load on the minor rails.

Infrared Images
Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).
The highest temperature our IR camera measured inside of the PSU was 72.7 °C, which is pretty low given our worst-case conditions.
