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.
