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.

  1. 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!

    1. I would also be interested to know more about this aspect.
      The Super Flower Leadex Titanium ATX v3.0 or ATX v3.1 1600W PSU models are practically non-existent anywhere except on newegg in america which has a 3.0 model.

  2. 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.
