Average Noise
The PSU’s average noise output is low at both voltage inputs.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The semi-passive operation doesn’t last long if you push the minor rails hard. Corsair also sets the minor rails’ max combined power at 150W, while most modern platforms keep it at 100W. The high combined power on the minor rails is a disadvantage in these tests. At up to 460W at 12V, the PSU’s noise is kept below 20 dBA. The PSU’s noise doesn’t exceed 30 dBA in these tests.
Fan Noise & Speed Maps @ 28-32 °C – 230V
The 230V fan noise profile differs slightly from the 115V one. The semi-passive mode lasts about the same, and the below 20 dBA operation is up to 505W, at 12V.
