Cross-Load Tests & 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
Don't expect to see over 90% efficiency with any load combination using 115V input. From 150W to around 790W, the 850 B3 falls within the 85-90% range. That's still admirable given this PSU's budget orientation.
Unfortunately, our sample broke down during OPP testing, so we didn't have the chance to shoot any infrared images with our FLIR camera.
