Super Flower Leadex VII XP 1200W ATX v3.0 PSU Review

The Super Flower Leadex VII XP 1200W is an ATX v3.0 PSU, which meets all requirements of the ATX v3.1 spec (and even more), so Super Flower could easily just change the logo and advertise it more efficiently.

The Super Flower Leadex VII XP 1200W will be included at some point in my best ATX v3.x & PCIe 5.x PSU picks article.

The Leadex VII XP 1200W has Platinum efficiency in the Cybenetics scheme and a Cybenetics Standard+ (35-40 dB[A]) noise rating. The unit’s dimensions are compact, with a depth of 150mm, which is low for its 1200W max power. Moreover, SF used an FDB fan to ensure the PSU would outlast the ten-year warranty. This is a top-performance power supply, as you will find out throughout this review, currently sold at a price notably lower than its direct competitors.

  1. Hello,

    I was wondering if this PSU is really atx 3.1 specification? If the connection is loose, will it short out and do the 0 watt/protection feature? Does it also have “Permitted on the 12V rail up to 13.75A for 0.1ms (165W), allowing for higher power draw from PCIe devices”?

    I understand this is a really good PSU, but at the same time the 3.1 spec is confusing.

    Thanks

    1. Hi! It is ATX v3.1 since Intel doesn’t require 12V-2×6, but it says it is mandatory only on the GPU.
      It can deliver 200% of its power for 0.1ms.

      It can be confusing indeed!
