Gigabyte AORUS GP-AP850GM PSU Review

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).

Efficiency Chart

We would like to see a region with over 92% efficiency, since this unit is 80 PLUS Gold certified.

Infrared Images

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).

Our IR camera revealed that the DC-DC converters can get quite hot, however we applied close to 10 Amps load in each of them during those tests, which is quite high and under normal conditions they won't have to handle such high loads. But we always have to take the extreme and toughest usage scenarios in order to be sure about our results and findings.
