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 1500 possible load combinations with the +12V, 5V, and 3.3V rails. The load regulation deviations in each of the charts below are calculated by taking the nominal values of the rails (12V, 5V, and 3.3V) as point zero. The ambient temperature is between at 30°C (86°F) to 32°C (89.6°F).

Efficiency Chart
For a quite large region the SF unit delivers more than 92% efficiency. We usually meet such high efficiency levels in 80 PLUS Titanium and ETA-A+ certified PSUs.

We apply half-load for 10 minutes with the PSU’s top cover and cooling fan removed before taking photos with our modified FLIR E4 camera that delivers 320×240 IR resolution (76,800 pixels).
The temperatures on the VRMs are high and probably this is why the passive operation doesn't last long.
The caps near the VRMs get quite hot as well, however from the moment they are polymers and not electrolytics, this won't be a problem. Moreover, under real life conditions the load on the minor rails will be much lower than the one that we applied during those tests.
