Average Noise
Look at the difference between the A850GLS and the A850GL models. It is chaotic! The 850GLS is among the quietest PSUs in the 850W category.

There is no semi-passive mode, but this isn’t a problem; the PSU’s fan operates at low speeds, even at loads of up to 450W, keeping its noise output extremely low. The fan exceeds 25 dBA of noise with more than 615W at 12V, and only for some minimal periods, its noise goes over 30 dBA. All in all, the fan speed profile is highly relaxed.
