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).

Efficiency Chart

From 175W to 345W on the +12V rail and with load on the minor rails held below 40W, the SF600 Platinum's efficiency lands within the 92-94% range. And as you can see in the graph, we get ?90% efficiency readings for much of this PSU's operating range.

Infrared Images

We apply a 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).

The PCB's hottest part is the daughterboard hosting the DC-DC converters, since we apply 12A of load on the 5V and 3.3V rails. Still, the temperatures we measure never get out of hand, so there's no reason for Corsair's fan profile to get aggressive.

    Less than 1% efficiency difference between Gold and Platinum ? Hard to make that pay under any normal use scenario.

    Glad to see that they made several other improvements for the Platinum model.

    I don't see the load chart.

    I just completed my ncase-m1 build with this. It's really good.

    8700K, 2080Ti. Like a boss. I'm not overclocking however (insufficient cooling for that).

    Looking forward to it. I will most likely get one for my next setup.

    Did you test the SF600 platinum with Vega graphics cards? I'm getting the OCP to trip on my just running the Vega 56 in turbo mode. The same thing was happening with my older Silverstone SX-650G power supply, and Silverstone confirmed that they had made an engineering change to fix the OCP tripping.

    It only happens in Destiny 2, no other games. I'm curious if this is a widespread issue, or something else with my system. It seems the Vega cards are tough on PSUs.
