Super Flower Leadex VII 850W Platinum Pro ATX 3.1 Fully Modular SMPS

The Super Flower Leadex VII 850W Platinum Pro (SF-850F14XP-ATX-3-1) is a fully modular power supply built to the latest ATX 12V v3.1 and EPS 12V v2.92 specifications, making it ready for modern high-performance gaming and workstation builds. Holding the 80 PLUS Platinum certification, it delivers 90% efficiency at 20% load, 92% at 50% load, and 89% at 100% load—minimising wasted energy and heat during every phase of operation. Cybenetics Platinum badges at both 115 V and 230 V inputs provide additional third-party validation of its efficiency across the full input voltage range. At the heart of the cooling system sits a 140 mm Fluid Dynamic Bearing (FDB) fan featuring a unique blade geometry engineered for high airflow with low acoustic output. The copper-shaft bearing construction improves thermal dissipation and extends the fan's operational lifespan. An ECO-mode Auto fan control function allows the fan to run at lower speeds—or stop entirely—under lighter loads, keeping your system whisper-quiet during everyday tasks. Cabling is entirely flat and flexible, simplifying installation and improving airflow inside the chassis. A patented universal 9-pin terminal on the modular panel connects to 12+4 pin GPU sockets (12VHPWR / PCIe 5.1) and can also serve PCIe, CPU, IDE, and SATA roles, reducing connector clutter. The buckle-style 20+4-pin motherboard connector uses Super Flower's patented design to prevent accidental disconnection, while full-range auto voltage detection (100 V–240 V, Active PFC) means it adapts to any mains standard without manual switching. Primary conversion relies on LLC resonance topology; the +3.3 V and +5 V rails use independent DC-to-DC conversion stages to maintain stable output under dynamic transient loads. All 105 °C Japanese capacitors are used throughout the main board and modular back-panel, supporting long-term reliability under sustained high-temperature conditions. The unit has passed more than 2,000 on/off cycle tests and is built with lead-free, RoHS/WEEE-compliant materials. A comprehensive six-layer protection suite—Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP)—guards connected components against fault conditions. ALPM mode and IEC/EN 62368 compliance round out the safety credentials. NVIDIA SLI and AMD CrossFireX multi-GPU configurations are supported, as are all Intel and AMD multi-core platforms.
