The Super Flower Leadex III ARGB Gold 750 W offers good performance and RGB lighting for the fan and all cube-shaped modular connectors. While both the non-RGB and RGB Leadex III use the same platform, I noticed a performance difference between the 750 W models, which probably comes down to my sample—it seems I am not that lucky when it comes to hardware. Still, overall performance is close to the competition, and thus far, no major brand, including Corsair, Seasonic, or EVGA, offers similar performance with RGB lighting for a PSU. If RGB and performance are important to you, the Super ARGB line is currently the only viable option.

Ripple suppression and load regulation are important, but so is transient response. It shows how well the PSU performs under real-life conditions, where loads change rapidly. The normal tests I run to check on efficiency, load regulation, and ripple performance don't show how the corresponding regulating circuits respond to fast changes in load, which is why I have to conduct another test where the dialed loads change so quickly I need a scope to "catch" the voltage deviations. While my feature-rich Chroma loaders can log these voltage deviations, I want to show you these deviations in scope shots for an idea of the voltage waveforms of such scenarios. All Leadex platforms are known for their excellent performance with transient loads, and the Leadex III ARGB Gold 750 W honors this tradition. Given transient response impacts a system's entire performance, you should pay close attention to this performance metric, especially if you want to use power-hungry, high-end CPUs and GPUs.

If you desperately want an RGB-lit power supply, your options are limited. Super Flower's ARGB line is a good choice, and the four models cover a wide range. The 750 W unit has many advantages. Its major cons are limited to the caps on the modular cables and the relatively short distance between peripheral connectors. In some mainboards, the high power-on time can also cause issues, which I advice Super Flower to address as soon as possible.
