Corsair SF600 Platinum SFX 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).

Load Regulation Charts

Efficiency Chart

From 160W to 390W load at +12V, and with the minor rails staying below 55W the efficiency levels exceed 92%. For a quite large operating range, marked with blue color, the unit's efficiency is in the 90-92% region.

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).

The temperatures stay low, although we pushed the minor rails hard. So it doesn't come as a surprise that we measure higher temperatures on the voltage regulation modules, used for the generation of the minor rails.
