The PCB is small and overpopulated on the secondary side, but all electrolytic caps are in the open without anything blocking airflow. The good airflow will help them since they are close to the 12V FETs, which will get pretty hot under high loads. What I don’t like so much is the vertical PCB hosting the fan header, which looks fragile if you want to remove the fan’s cable. This design that Super Flower used in the past in the EVGA Leadex-based units led to the failure of some of my review samples until I decided to enhance the base of this vertical PCB with silicone before I attempted to remove the fan header.
The blue PCB looks nice, and to save space, Super Flower installed the VRMs, generating minor rails on it instead of a vertical board. This is something I didn’t meet before, as I recollect, at least since something may slip after thousands of PSU reviews.
On the primary side, besides the APFC converter, four FETs, arranged in a full-bridge topology, chop the incoming signal to feed the main transformer, which provides power to the secondary side. An LLC resonant converter is also used to minimize switching losses. Sixteen (!) FETs handle the 12V rail on the secondary side, and two DC-DC converters generate the minor rails.
The soldering quality is good, especially for an early production unit, and all parts that SF used are of high quality, including the FETs and the capacitors. As for the fan, this is provided by a relatively new and promising, as it seems, brand. Let’s see if a new brand will question Hong Hua’s dominance in the PSU fan market.
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 🙂
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.
