darkFlash UPMOST 1250W ATX v3.0 PSU Review

Average Noise

The PSU’s average noise output is high at both voltage inputs.

Fan Noise & Speed Maps @ 28-32 °C – 115V

The semi-passive mode doesn’t last long, and to make matters worse, the fan starts at some point with its noise in the 35-40 dBA noise, which is annoying. The 30 dBA mark is passed early, with just 280-350W loads at 12V, and the PSU enters the 35-40 dBA zone at 525W. Noise exceeds 40 dBA at 710W, and if this wasn’t enough, you will be treated with over 45 dBA if you dare load the 12V rail with more than 920W.

The 230V fan noise profile has some small differences from the 115V one, leading to a slightly lower average noise output.

  1. UPMOST? XD
    It’s nice to see that there is so much optimism and imagination around.
    This should lead to improvement.
