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

The Super Flower Leadex VII Gold 1300 is the stronger PSU from this manufacturer, offering ATX v3.0 and PCIe 5.o compatibility. 

After the Leadex VII Gold 1000W review, the time has come to look at the 1300W model, which has the same cable configuration, dimensions, and cooling fan. The notable difference is the increased max power by 300W, which provides more headroom for highly overclocked CPUs and GPUs. Given that some RTX 4090 graphics cards can exceed 500W under load, and CPUs like the Intel 13900K can get close to 200W, someone may wonder if there is a point in having such strong PSUs available on the market. At stock clocks, power requirements are as mentioned above, but at overclocked speeds, these numbers can notably increase. From the moment a high-capacity PSU has the same efficiency under typical loads, if not higher, compared to a lower-capacity PSU, there is no harm in getting a stronger than 1000W unit for a high-end system. Moreover, you should not get a PSU with maximum power close to your system’s peak power needs because, in most PSUs, peak efficiency is at typical loads, 40-50% of their max-rated capacity. If your system averages 500W power consumption, it is ideal for getting a 1000W unit.

The Super Flower Leadex VII Gold 1000 is a high-capacity PSU that meets the ATX v3.0 and PCIe 5.0 requirements. It has compact dimensions, measuring 150mm in depth, and is equipped with a 140mm fan from a brand I had never heard of before. Hong Hua fans, widely used nowadays, might be out of reach for smaller production manufacturers, so SF had to use another brand.

  1. 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.

  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. 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,
