Given the platform’s design and parts, the OCP triggering points are conservatively set, but I would like to see a difference between the hot and cold OCP triggering points. The same goes for the OPP triggering points, which are identical! The rest of the essential protection features are present.

May I please ask, why is there no review of the Leadex VII XG 850w? It’s highly recommended but I can’t find the review.
Thanks again for the wonderful work.
Do you think Super Flower Leadex VII Pro 850W is still a great option despite high In-rush current?
Other options I have are Deepcool PX850G, Corsair RM850e and XPG Core reactor II.
So what do you recommend ?
Yes it is a good option, because you won’t be able to drain that easily its bulk cap in normal conditions.
Full bridge: 4x main FETs
Hald bridge: 2x main FETs
I would leave it on the fan working mode, and let the fan adjust its temperature based on the thermal load.
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.
Based on your experience, in these models that come with fans with ECO or hybrid mode, do you recommend always using the fan on or having it work automatically based on temperature?
Hello, could there be an error in the characteristics? What is the correct full-bridge or hall-bridge topology?
thank you and greetings
