Average Noise
The PSU’s average noise output is below 30 dBA at both voltage inputs I tried, but still not competitive.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The semi-passive mode operates at approximately up to 250W at 12V, with a minimal load on the minor rails. Higher loads on the minor rails restrict the semi-passive mode’s operation. Once the fan starts to spin, it does so at high enough speeds to produce over 25 dBA noise. Typically, there should be several intermediary modes to offer a smoother transition to the fan’s louder operation. With more than 800W at 12V, noise exceeds 30 dBA, and the 35 dBA mark is passed at around 880W. All in all, the fan speed profile requires further refinement to reduce the unit’s overall noise output. A less restrictive fan grille would also help.

The 230V fan speed profile minimizes the 30-35 dBA range, and the 35-40 dBA zone is also a bit smaller, so the average noise output drops.
Hi Crmaris. Thanks a lot for all your reviews and instructive knowlegde! I’m building a mid-tier mATX system with a 9600X/9070XT combo. After going through multiple reviews I’m doubting between 2 PSU’s, both around the same price:
XPG Core Reactor II VE 850W ATX v3.1
or
Montech Century II 850W ATX v3.1
Which one would you recommend? (if not a third option 😉
Thanks in advance
As far as i’m aware the 850W version is based on a different platform. Does it hold up to the 1050W/1200W versions or should i avoid it?
Slightly diff platform but still scored an “A-” rating, very good PSU, I have one in my build.
Thanks for a review crmaris. Will you be doing a review of PCCooler YS1000?
I think I have them too somewhere 🙂
