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.

Is it just me or could the PSU have performed significantly better in ripple suppression and transient response if they hadn’t gone with such an extremely low amount of secondary caps on the secondary side?
I count 27 caps or which many are fairly small. Other manufacturers like Seasonic are liable to use over 50 caps in that power class.
Yes the form factor is small but they definitely had space for more caps on the breakout board. They cheaped out, which is a pity.
Aris would you review Antec SF850X & Gamemax GX-1050 PRO ?
if they send them to me sure 🙂
UPMOST? XD
It’s nice to see that there is so much optimism and imagination around.
This should lead to improvement.
