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).
Load Regulation Charts
The high efficiency region is from 120W to around 450W at +12V, with the load on the minor rails staying below 95W. In the majority of its operating range the unit delivers within 85-90% efficiency.
The 5VSB rail’s ripple graph is colorful! The vivid colors might look nice, but actually depict a ripple suppression problem.
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 caps close to the chokes of the secondary side get quite hot, and this can be a problem since they belong to Teapo’s mainstream SC line. Other than that, we don’t spot anything strange in those IR shots. The temperatures in the rest components are kept at normal levels, considering this platform’s efficiency.
