We would like to thank Super Flower for supplying the review sample.

Since I have evaluated every Super Flower Leadex III ARGB Gold (ETA-A on the Cybenetics scale) PSU but the 650 W unit, I felt it needed some love too. 650 W is enough to build a strong gaming system equipped with an Nvidia RTX 3070 or the upcoming AMD RX 6800. Besides the RGB fan, crystal cube connectors, and two instead of three ECO modes, there are no differences between the ARGB and non-ARGB Leadex III models. The latter are notably more affordable, with price differences ranging from €20 to €24. If you fancy RGB lighting, this is a small premium to pay, and you get the cube connectors, which look much better than the standard Molex connectors.

The Leadex III ARGB Gold 850 W, 750 W, and 550 W units performed excellently, so I have high expectations from the 650 W model.

Since no longer bound by their now expired EVGA "pact," Super Flower has entered the US market on its own. You will find their products on Newegg, but there might not be enough stock because of COVID. In Europe, two major online stores import Super Flower PSUs, and, and prices for the four Leadex III ARGB models with 550 W to 850 W maximum power output range from €110 to €150 including VAT.
