The Super Flower Leadex III ARGB Gold with 850 W maximum power output performs well and has excellent transient response at +12 V, which is what matters the most in real-life scenarios. Its 5VSB efficiency is also pretty high, and Super Flower used quality parts, although the soldering quality is not the best I have seen by this manufacturer. The main problem of this model is its increased price over Leadex III models without ARGB. If you don't need lighting, you are better off getting a plain Leadex III unit to save some money. That having been said, if you have a windowed chassis that shows off the PSU and you want an ARGB-lit PSU, the Leadex III ARGB is still for you.

The competition is fierce in this wattage category, and the Corsair RM and RMx units score higher than the Leadex III ARGB. I also noticed that the EVGA 850 G3, also based on a Super Flower platform, achieves a higher overall performance score, which means Super Flower still needs to make changes to this platform to catch up with the competition and outperform its previous platform. When it comes to noise output, this model features a quiet operation, but the gap to the Corsair RM850x and Fractal Design ION+ 860P is still vast. Super Flower should also take a look at the power-on time, which is way above the required levels of the ATX specification.

If you are after an RGB-lit power supply, you don't have many choices in this wattage category because both Corsair's and EVGA's mid and high-tier models don't have RGB. Super Flower chose to provide this option, but at an increased cost over the non-ARGB Leadex III models. The Leadex III ARGB 850 W is a fine unit that can be even better with a few changes, and there is of course always room for improvement when it comes to the retail price. Finally, it is nigh time for Super Flower to enter the US market, which will allow for larger production volumes and, consequently, price drops. The only problem is that doing so would demand a well-organized distribution and support channel for handling RMAs, which isn't cheap, so I expect it to in turn increase pricing.
