  1. Which PSU would you chose? Same price. 230V.
    Considering wattage: current PC (7500F, 7900 XT), future PC (7900X3D and 8900 XTX level of combination).
    Prefer fan not to spin on and off all the time.
    Longer eco/silent mode preferred.

    – Super Flower Leadex VII XG SF-1000F14XG BK
    – FSP Hydro G Pro HG2-1000 Gen5

  2. I am building a new PC with a Ryzen 7900X and RX 7900XTX. Would the Super Flower VII Leadex Gold be a better option than the NZXT C1000 3.1 version?

  3. 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 Caseking.de 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)

  4. 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!

  5. 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

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

  7. 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?

  8. 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

  9. 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.
