Load regulation is within 1% at 12V and 5V, but loose at 3.3V.

Ripple suppression is increased at 100% and 110% load levels at 12V. This was the case in the 1000W unit, too. On the other hand, ripple suppression is good on the minor rails.

Hello Aris!
Trying to decide between this PSU and the Corsair Rm850x ATX 3.1 version – the Corsair allows manual fan rpm control, and my Lancool 207 case allows only downward fan orientation, would this be an issue for Power Zone 2 and make the fan start/stop intermittently since it has no manual control? Would you say the be quiet is the better pick overall since it has better Cybenetics ratings? Thanks for your reviews and hard work!
PowerZone 2 has better noise rating, I have this PSU I never hear it. The problem is I measured mine and it exceeds 160mm which is the size limit for the Lancool 207 that I want to get. Were you able to fit the PSU and route the cables through, do you use the 12v power connector that’s sensitive to bending? This is what I’m worried about.
I found some other comment about this PSU and Case combo but no mention about that nvidia problem cable.
I got the MSI MPG A850G instead because of better availability/price in my area. It is also 150x150mm, so more cable space than the others would have, but I think 160mm would still be manageable. I haven’t tried the 12v, but it could be concerning. The one included with the MSI is pretty stiff, and would probably have to bend even with the extra clearance. Maybe a more loose/flat cable would work better in this case.
