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


Super Flower’s new Leadex VII Gold PSUs look promising, given the results of the 1000W model. Compared to the previous generation of Leadex units, the design is different. The larger PCB allows for higher airflow; hence, noise output is lower than the Leadex V Pro Platinum with a similar capacity. Efficiency is high, with the PSU achieving a Platinum rating on the Cybenetics scale, although Super Flower rates it as 80 PLUS Gold.

The build quality is high, with the only questionable point being the cooling fan, which is from a brand I never saw before, so I cannot know its reliability through time. Load regulation is tight, ripple suppression is good, the transient response is decent, with the unit meeting the tough ATX v3.0 requirements in transient loads, and the hold-up time is long. Regarding PSU timings, I would like a lower than 100ms Power-on time (T1) for increased compatibility with mainboards. I will discuss this with SF to fix it before these PSUs hit the market. SF should also increase PF with 230V input. This is something that most manufacturers miss, high PF readings at 230V because they emphasize 115V. Lastly, seeing an efficient 5VSB rail at both voltage inputs I tested, 115V and 230V.

The Super Flower Leadex VII Gold is a great power supply, keeping up with the good name of this series. It was high time to see ATX v3.0 offerings from SF, and I hope they will release them soon in the market. So far, I don’t have any pricing information. Once SF informs me about it, I will update the review.

  1. 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.
