Transient response at 12V is not among the best in this category. You cannot call it mediocre, but it is not great. This is because of the increased voltage drop during the 20% transient response test, where the PSU’s resonant controller operates in PWM mode.
Transient Response ATX v3.0 Tests
The PSU successfully passed all ATX v3.0 transient response tests.

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?
Both are very good. Just get the one with better support in your region.
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.
for me anything above 5-years for a PSU is overkill. Doesn’t do any good to either consumers and brands.
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?
Super Flower, you also have a valid point. From now on, I will completely stop mentioning warranty periods on the pro list.
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)
I removed for quite some time now the warranty from pros. I don’t want to encourage brands to provide “unrealistic” warranty periods.
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!
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
Most likely it does, yes.
is the Super Flower Leadex VII Gold is atx 3.1 compliant because the platinum pro version is not yet available in canada
Yes, it is.
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?
It is a very good PSU, according to my test data.
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?
Super Flower one
you mean Sense cables? You don’t need to worry about them.
is the 850w version full-bridge too?
Don’t remember sorry.
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
is the 850w version also full-bridge?
Is there any information when this PSU will be released in Europe?
Why no inclusion of other atx 3 psus you tested like Msi etc? This doesn’t seem best way to inform users
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.
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.
Thank you! I will review these in time. The lab’s move cost me lots of time unfortunately.
it looks good. Thanks
