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
The PSU achieves greater than 85% efficiency from 90W to 450W load on the +12V rail, so long as load on the minor rails stays below 80W. You shouldn't expect more from an outdated platform.
We applied 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 320x240 IR resolution (76,800 pixels).
Temperatures inside of the Caslon II are high due to its low efficiency. This proves that a loose fan profile was simply not an option during this PSU's design.
