Super Flower Leadex VII Gold 1300W (SF-1300F14XG) PSU Review


Super Flower’s new Leadex VII Gold PSUs look great, given the results from the 1000W and 1300W models. Especially the latter topped my charts, leaving notably behind units like the XPG Cybercore II 1300 Platinu, the Corsair HX1500i, Thermaltake Toughpower GF3 1350W, and even the Titanium efficiency be quiet! Dark Power Pro 12 with 1500W max power. It took Super Flower a while to release ATX v3.0 and PCIe 5.0 ready PSUs, but the results are outstanding. Its engineers still got the magic recipe for high performance, and with a bit of tuning of the fan speed profile, the result will be even better.

I remember back in the day when most users weren’t aware of Super Flower models and thought that it was just another Asian manufacturer with mediocre products. Still, its cooperation with EVGA made this brand widely known, and now it is working on its own mainly, trying to sell its products under its name, and so far, from what I hear, they go well in challenging markets, like the US one. I look forward to when the Leadex VII units will hit the market and at what prices because I don’t have this information yet. If SF manages to throw them on the market at reasonable prices, the stock will most likely vanish soon, so grab them when you can.

  1. Hi Crmaris,

    When will this psu be released in eu?

    I cant find a good 1200 watt ATX 3.0 psu in europe.

    Nothing comes close to this cpu as far as i know. What should i do or buy tom come close to this psu? Im lost. Biggest factor for me is noise and coilwhine.

    Kind regards,

  2. I needed a high wattage PSU and decided to buy this on Newegg for 185 USD largely based on this review. Many of the 1000W PSU featured on this site was priced 140 USD and often more according to PCpartpickers, so it wasn’t that hard of decision to pay a little extra for this instead.

  3. no case is included on the current release of this PSU. I think all PSU’s should come with a case/bag. Feels very cheap to see it in this review but not in the retail release.

    Not a reason to avoid but something to note. The cables felt a lot less substantial than a msi 1000w unit I was pulling out (DOA unit being returned). The MSI MPG also had nice sleeved cables while this one had more standard ones with very poor QC on the rubber tape/band wrapped around the 12VHPWR. Glue was allowed to seep and dry from the tape and just made everything look sloppy. Not what someone wants to put in their 3-4k PC.
