Average Noise

The average noise output is high.

[115V] The passive operating doesn’t last long using a load pattern that fully stresses the minor rails. The problem is that once the fan starts to spin, it quickly increases speed, outputting higher than 25 dBA noise. At 500W, the 30 dBA mark is passed, and at 660W, the PSU’s fan is above 35 dBA. Lastly, with more than 800W, the noise goes over 40 dBA. The PSU’s fan speed profile could be improved, especially at light loads. Moreover, a less restrictive fan grille would help.

  1. Hi, confused on the review. In the first page it alludes to the 1250W version and also says it’s Platinum efficiency but specs and picture shows Gold.

    If its 1050W, ATX 3.0 and Platinum, it would be the perfect one for me so unsure on the details provided. Thanks.

  2. It is Platinum in Cybenetics, while Gold in 80 PLUS. Cybenetics measures efficiency using a different approach than 80 PLUS, taking thousands of measurements instead of only 3-4.

    So the 1050 is Cybenetics Platinum, while the 1250 is Cybenetics Gold.
