Load regulation is tight enough at 12V and extra-tight on the minor rails.

Ripple suppression is excellent at 12V but on the high side on the minor rails.

Great review as always, thank you aris.
I wonder what happened to the digital psu platform that Superflower showed way back during Computex 2015, it was never mentioned again outside of that event.
Super Flower Leadex Titanium ATX v3.0 1600W PSU
I cannot find a Super Flower Leadex Titanium 1600W PSU that also denotes it as ATX v3.0 compatible.
I’ve seen ones with a box exactly as you depict in this review (which also does not say ATX v3.0 on it anywhere), with everything the same except without the 600W PCIe 5.0 / Gen 5 12VHPWR PSU Cable. I have seen that cable available separately however and it states it is compatible with the Leadex 1600W Titanium.
I think the only Super Flower PSU’s I’ve seen that denote ATX v3.0 on them are the Leadex VII XG’s.
So I am a bit confused. Can you clarify the ATX v3.0 compatibility of this unit?
Thank you for all your testing and posting it for us to review!
