Average Noise
The average noise output is close to 27 dBA at 115V input and around 26 dBA at 230V. Overall, this is not a noisy PSU.

The semi-passive mode features a slight break between 65W and 90W, with the fan’s noise falling within the 20-25 dBA range. Noise output is kept low at up to around 400W at 12V, and the load on the minor rails doesn’t significantly affect the fan speed profile. MSI did well to keep the max combined load on the minor rails at 100W. With higher than 430W at 12V, noise enters the 30-35 dBA range, and the 35 dBA mark is passed at 490W.

The 230V fan speed profile has some differences, with the most notable being the three periods of fan stop, instead of two at 115V, and the longer duration of the 20-25 dBA range.
