Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 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. The ambient temperature was between at 30°C (86°F) to 32°C (89.6°F).
Load Regulation Charts
This is a very efficient PSU. As you can see in the chart above, between 150W and 680W load, at +12V, and with the minor rails not hugely stressed, efficiency registers greater than 90%.
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).
According to our FLIR camera, temperatures inside the PSU are very low. This is all but assured by high efficiency and a fast-spinning fan.
