SUPER Flower Leadex III 850W 80+ Gold ATX 3.1 Fully Modular Power Supply

The Super Flower Leadex III 850W (model SF-850F14GE) is a fully modular ATX 3.1-compliant power supply designed for modern high-performance desktop builds. Carrying the 80 PLUS Gold certification, it is engineered to deliver efficient, stable power to demanding gaming and workstation configurations. As an ATX 3.1-compatible unit, the Leadex III 850W supports PCIe 5.1 connectivity and can handle up to 200% power excursion, a key requirement for the transient spikes produced by modern discrete graphics cards. The modular panel uses HCS (High Current Socket) terminals with dual 8-pin sockets that connect to a 12+4-pin connector on the GPU side, a design intended to reduce stress from high-angle cable bending. All cables are fully detachable ultra-flexible ribbon cables, allowing for clean routing and tidy cable management inside the chassis. Only the cables you need are installed, reducing clutter and improving airflow. Cooling is handled by a 140 mm fluid dynamic bearing (FDB) fan featuring a unique 7-blade design. FDB fans are widely recognised for low noise output, precise RPM control, and extended operational lifespan compared to sleeve-bearing alternatives. The copper shaft around the bearing further aids heat dissipation and mechanical stability during extended operation. Internal quality is anchored by a Japanese main capacitor, a component commonly associated with greater thermal tolerance and longevity in power supply designs. The unit also conforms to IEC/EN 62368 safety standards and supports ALPM (Active Link Power Management) mode for platform-level efficiency features. Eight protection circuits are built in: Over Voltage Protection (OVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Temperature Protection (OTP), No Load Operation protection (NLO), and Surge & Inrush Protection (SIP).
