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
For the most part, we observe efficiency levels between 85-90%. If your system draws less than 180W under normal conditions, you're better off investing in a higher-efficiency PSU. Otherwise, if you anticipate high utilization most of the time, and you cannot spend more on a PSU, the 750 B3 will fare well enough.
Unfortunately, our sample died during OPP testing, so we didn't have the chance to shoot any infrared images with our FLIR camera.
