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 is included 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.

I’m sorry i’m not very knowledgable in PSU and someone at a local shop suggested me the Super Flower Leadex VII XP 1200W.
is what you just said a good thing? i’m currently building a high end PC with a 9800x3d with hopefully a 5090.
Kinda afraid to buy something i don’t know much of the brand and not much review overall exept i know HWB is very reliable according to these things but their seems to be difference in what model they advertise.
This PSU is top-notch!
Hi,
βBuy Super Flower Leadex VII XP 1200Wβ button leads to Newegg page with a PRO version of this model which is very different (unknown to me at the time of order). I didnβt see 1200W PRO review on this site (is there one?), however, according to 1000W PRO version review the PRO model is way worse than non PRO.
Should I cancel the order of Super Flower Leadex VII XP 1200W PRO?
I am very confused too. I can only find the VII Pro on the internet with the SF-1200F14XP SKU from the XP
The VII Pro is also good. They renamed a model I think. I will ask them again because SF’s model names are a complete chaos!!!
I talked to SF about this. the XP is the Pro!!! They renamed it…
So the Super Flower Leadex VII XP PRO from Neweggs is indeed the one you reviewed? You think it’s worth and is highend enough for a 5090/9800x3d combo?
leadex vii xp1200 platinum or leadex vii xg 1300 gold, price is similar. Which one is better for amd 9950x + 5090 GPU? Thank you.
I would go for the XP unit
Hi,
Thanks so much for reviewing this unit, very helpful as I’m looking to upgrade in a way that also allows sufficient headroom to use next generation GPUs.
Looking at the latest versions that are up for sale it appears as though Super Flower has changed the connector design to what they are calling their “universal Super Connector”. I would imagine this doesn’t have any impact on the performance of the unit but I am by no means an expert.
Also with rumors that next gen GPUs could require 2x 12VHPWR, would the use of universal connectors enable this (with a combination of a 12+4 and 2×6+2 cables)?
Are you sure you reviewed the XP model here and not the XG ? because the photos on your site and the photos on the manufacturer’s site don’t match up ,on the manufacturer’s site XP model has different connector plugs on the psu side.
this was an early sample and because of my results, they changed the model’s number. Actually because of Cybenetics ratings.
Hi Aris,
i am still a little bit confused. On their website Super Flower lists a XG (Super Flower Leadex VII XG) and a XP (Super Flower Leadex VII Platinum Pro) series, both Cybenetics Platinum certified.
Your Cybenetics measurements for both series are almost identical. Except for different cable lengths, is there any difference between those psu’s? Or is this only a relabeling because of your cybenetics rating? In germany the XP and XG 1000w models cost almost the same. Assuming the price stays the same, which series would you recommend?
Thanks π
Hi! We don’t do re-labeling, we have to check everything.
SF followed/thought according to the 80 P scheme. They will start thinking according to Cyben’s schemes from now on. If they cost the same, XP.
At the same prices, which is better and do you recommend buying seasonic Vertex platinum px 1200 or leadex vii 1200 platinum or leadex vii 1300 gold ?
thank you.
Where you found/buyed it in Germany?
I want it too.
SF sent it to me, I didn’t buy it. Sorry no clue where you can find it in Europe.
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
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!
Hello, Superflower has released this 1200 model in PRO version, with other types of connectors, I don’t know if it has more internal differences and is superior to the one in the review, are you going to do an article on the new 1200w model?
thank you and greetings.

As the previous author, I am also wondering if this PSU as part of new ATX 3.1 standard will send open open signal when nothing is connected to the high power plugs? If not, does it mean itβs not 3.1? Recently I have ordered this model in PRO version.
If anyone is interested, bellow is a reply by super flower customer support.
The PSU SF-1200F14XP is both ATX 3.0 & 3.1 certified. You may find out the certification in below charts (from Intel PSU Selector & Cybenetics Labs).
It includes a 12V-2X6 cable with 2sensor pins as Ground-Ground for 600W Output. The open-open revision happens on GPU socket. It detects the provided cable to draw the power consumption.
The included cables can be plugged into any 9 universal plugs as they are universal.
They are able to supply 600W on demand.
