Average Noise
The PSU’s average noise output is dead low, given its capacity.
Fan Noise & Speed Maps @ 28-32 °C – 115V
Because of the load pattern that I apply, the fan’s semi-passive operation doesn’t last long, but the fan’s speed is within 400-600 RPM at up to 1050W, so the noise output is below 6 dBA. Actually, the fan’s noise doesn’t exceed 6 dBA at up to around 1120W. Moreover, the fan’s noise doesn’t exceed the 30 dBA mark, even at full load. Compared to the “plain” TX-1600, the average noise output difference is 8 dBA, which aligns with what Noctua claims.

The 230V fan noise profile is almost similar to the 115V one.

Thank you for the through review. Did you test for EMF? I don’t recall seeing it in the review.
EMI? Nope.
it’s up there with the 1kW (or more) passive PSU on the: impressive feat, but what for? list
with such a high load components you use absolutely will make tons of noise, even the beast won’t be able to handle them, so… it’s beyond flagship, it’s just a showoff
unless some users use custom water cooling with silent fans and huge radiators.
