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 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 650 G1+'s efficiency landed in the 90-92% range from 125W to 490W on the +12V rail, with load on the minor rails staying below 90W.
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 320x240 IR resolution (76,800 pixels).
Temperatures inside of the PSU were normal, meaning that EVGA's SuperNOVA 650 G1+ could have easily supported semi-passive operation.
