Average Noise
The average noise output is close to 30 dBA at 115V, but it could be lower given the platform’s high efficiency. It drops notably lower at 230V.
Fan Noise & Speed Maps @ 28-32 °C
[115V] If selected, the fan’s passive operation lasts long, restricting the PSU’s noise at light and moderate loads. At higher loads, the fan speed profile gets weird, with the 30 dBA mark passing at 590W at 12V and with some regions where noise even exceeds 40 dBA. If you keep the combined load on the minor rails below 80W, you won’t have over 40 dBA fan noise, and if you remain below 60W max combined load on the same rails (5V and 3.3V), the noise will stay below 35 dBA at high loads. The small regions where you see increased fan noise at 12V, between 670W and 820W, are because the increased load on the minor rails, in previous load circles, keeps the fan’s speed high, although the load on the minor rails is dropped. It takes some time for the fan speed to settle down after a high-speed region.

Regarding the high inrush current
will the high inrush current damage both the PSU and external voltage stabilizer in the long run? I currently use this PSU alongside a 1000 VA stabilizer.
everything is affected, but note, high inrush currents exist ONLY if the bulk cap is completely drained, something not that easy.
I’m not really familiar with electricity,
does turning the PC off for days completely drain off the bulk capacitor?
Also, will you still rate leadex vii pro as good as leadex vii XG?
I was going to buy leadex vii XG since you rated it as the best overall performance, but it was out of stock in my country, so I bought the leadex vii pro
Usually not. The bulk cap usually keeps a charge unless the PSU is off for a significant period, week, or even months. The XG seems to have slightly higher performance but you won’t notice it. You made a very good choice to buy the Pro, no worries.
Is the only difference between this line and the XG line 3.0 vs 3.1 compatability?
they have hardware differences.
Hello, are these manufacturing differences for better or worse? in my country the leadex XG 850 and the leadex XP Pro 850 cost the same, after reviewing both and seeing the problems with the Pro, which one would you choose? Do you plan to review the leadex vii xp 1200 Pro?
The XP model. This 1200W model if they send it yes.
