Conclusion
Today, building a gaming PC powered by the latest NVIDIA RTX graphics cards that use the 12V-2x6 connector would require at least a PCIe 5.0-compliant model. The LEADEX III GOLD UP ATX 3.1 series is Super Flower's flagship 80 PLUS Gold-rated PSU that features ATX 3.1 and PCIe 5.1 standards. It is positioned as a mid-range offering second to the LEADEX VII PLATINUM PRO ATX 3.1 which is the brand's latest 80 PLUS Platinum-rated PSU with the same ATX 3.1 and PCIe 5.1 standards.

The LEADEX III GOLD UP ATX 3.1 series offers an impressive set of features. Those that would be notable to builders include the compact size, the intelligent cooling fan modes, and the availability of black and white models for colour-matching with the rest of your PC.

Acoustics of the LEADEX III GOLD UP ATX 3.1 is excellent, users can run it on a semi-fanless operation using Modes 0 and I. Super Flower’s fan modes are based on temperature not load which is a good take on intelligent fan control. Temperature is the better variable to control the PSU’s cooling given that room temperature plays a larger role in the component’s temperatures compared to load. For example, lower room temperatures during winter subject computers to require less active cooling. Hence, PSUs like the LEADEX III GOLD UP ATX 3.1 could run its semi-fanless modes more efficiently in such a scenario. The PSU's FDB fan runs silently even at loads above 50%. In gaming, it would still be the graphics card and CPU cooler that would be the louder source of noise during computer operation.

The LEADEX III GOLD UP ATX 3.1 features a powerful 12V+ rail based on our testing with tight voltage regulation well beyond the Intel voltage regulation. The flat cables are flexible and easy to manage. The white model comes with flat white cables to colour-match white gaming PC builds.



The Super Flower LEADEX III GOLD UP ATX 3.1 850W power supply unit has an MSRP of £139.99/US$139.99 which sits in the middle of the pack among other 850W fully modular 80 PLUS Gold offerings that have 12V-2x6 connectors. However, it is currently the cheaper offering when it comes to ATX 3.1 and PCIe 5.1-compliant models. The LEADEX III GOLD UP ATX 3.1 Series comes with a 10-year warranty. Super Flower is the OEM of the world-renowned EVGA PSUs with a good track record for reliability. The LEADEX III GOLD UP ATX 3.1 Series is an ideal PSU for builders today looking to adopt the 12V-2x6 standard with its good performance, smart cooling, compact design, and long warranty coverage.
