Super Flower Leadex VII Gold 1000W (SF-1000F14XG) PSU Review

The Super Flower Leadex VII Gold 1000 is among the first ATX v3.0 and PCIe 5.0 compatible PSUs from this manufacturer, offering high performance, keeping up with the Leadex models legacy. 

Super Flower became known worldwide through its collaboration with EVGA, which brought us products like the legendary G2, P2, and T2 models. There were times when Super Flower led the race in performance and efficiency. Still, it stopped being in the spotlight for several reasons, especially when its exclusive cooperation with EVGA ended. EVGA is now in deep financial problems, and Super Flower is pushing more on selling products under its own name, as Seasonic does, and doesn’t seem to care so much anymore for selling platforms to other brands. I am happy to see Super Flower pushing new products on the market because this manufacturer has potential. We need more players in the field to provide potential buyers with a wider range of options.

The Super Flower Leadex VII Gold 1000 is a high-capacity PSU that meets the ATX v3.0 and PCIe 5.0 requirements. It has compact dimensions, measuring 150mm in depth, and is equipped with a 140mm fan from a brand I had never heard of before. Hong Hua fans, widely used nowadays, might be out of reach for smaller production manufacturers, so SF had to use another brand.

  1. Hi,
    quite like this homepage with all the tecnical knowledge and the way to teach it to publics.
    One thing I would like to know is whats about the 10 year warranty for SuperFlower.PSU`s.
    This homepage/review is the only place I did find this information. Not even on SuperFlower`s homepage I can find informations about the lifetime of the warranty.
    It would be more transparent to clear this, because warranty is a big argument in the PSU-business. Otherwise it looks like this brand gets pushed undeserved.

      1. Yes, that may be the case, but if you write 10 years warranty on the “Pro list” in your test report, I would like to find this information somewhere else as well. SuperFlower does not communicate a warranty period on its homepage, nor does as the probably largest European reseller.
        From where do you have this information?

          1. Yes, think this would be consistent and straighforward.

            Like you said before. Warranty is not such a important argue and apart from this, every brand has its own service and understanding of warranty. There is no standard. (don`t mistake with the two years warranty from the seller)

  2. I might also stretch my budget +20 euros more and get the Super Flower Leadex VII XG 1000W that was reviewed here and call it a day? Or it will be an overkill for my rig? Thanks!

  3. I am currently building my new rig Based on AMD team with ASRock B650M Pro RS WiFi, Ryzen 7 7700, ASRock RX 7900 GRE Steel Legend OC. And for the PSU i am skeptical and i was wandering if the Super Flower Leadex VII XG 850W has the same Japanese caps like the 1000 watt sibling. Is it worth the 150 Euros that they ask? Thanks

  4. is the Super Flower Leadex VII Gold is atx 3.1 compliant because the platinum pro version is not yet available in canada

  5. Hey , would you recommend Asus Rog Strix 1000G Aura Gaming? I can’t find a review about it but it is on your comparison chart.I am torn between Super Flower Leadex VII GOLD ,Asus Rog Strix Aura Gaming and Seasonic Vertex GX – which one would you choose?

  6. Hey Aris im Stuck between the Seasonic GX-850 ATX3.0 , RMX shift 850 and the Super flower VII which unit would you purchase personally?

      1. Hi! I just bought a superflower leadex vii 850w xg. Was wondering where do the 2 small cables from the 12VHPWR cable connect into the 2×8 ( which is actually 6 pins). Have not been able to trace these small cables.
        Thank you

  7. Why no inclusion of other atx 3 psus you tested like Msi etc? This doesn’t seem best way to inform users

    1. Different categories, the MSI unit I reviewed is digital and more expensive. I also try to keep the graphs small enough for mobile browsing. I can input 200x PSUs if I wanted, but the graphs wouldn’t be usable.

      1. Great Reviews..I have looked at almost all of them trying to learn and assume what certain things mean. Straight power 12 850 watt , seasonic vertex 850 watt, and either of those two models in 1000 watts. I hope you review. Trying to figure out which one is best. Either way great info sir.
