SUPER FLOWER Leadex VII 850W 80+ Platinum Pro Fully Modular ATX 3.1 Power Supply ( 850W ) ( Black )

The Super Flower Leadex VII Platinum Pro 850W (model SF-850F14XP-ATX-3-1) is a high-performance, fully modular power supply built to meet the latest ATX 12V v3.1 and EPS 12V v2.92 specifications. Designed for demanding gaming and workstation builds, it delivers 850 watts of continuous power with 80 PLUS Platinum certified efficiency — achieving 90% at 20% load, 92% at 50% load, and 89% at 100% load, minimising energy waste and heat output across all usage levels. Cooling is handled by a 140mm fluid dynamic bearing (FDB) fan featuring a uniquely profiled blade design engineered for high airflow with reduced acoustic output. The copper-shaft bearing design enhances rotational stability and heat dissipation, contributing to a longer operational lifespan. An Auto and ECO fan control mode allows the fan to remain off or spin slowly under light loads, keeping your system near-silent during everyday tasks. The Leadex VII Platinum Pro is fully modular, meaning every cable — including the ATX main connector and CPU power leads — detaches completely from the unit. All cables are flat ribbon-style for easier routing and improved airflow inside the chassis. Super Flower's patented universal 9-pin terminal system on the modular backpanel supports PCIe, CPU, IDE, SATA, and 12VHPWR connections from a single connector format, reducing compatibility concerns. The included HCS terminals and dual patented 9-pin Super Connector to 12+4 pin GPU-side socket supports up to 200% power excursion as required by the ATX 3.1 specification, making it ready for the latest high-TDP discrete graphics cards. Internally, the unit uses 100% Japanese 105°C-rated electrolytic capacitors on both the main board and modular backpanel, alongside polymer solid capacitors, ensuring stability and longevity. LLC resonance conversion handles the primary stage, while DC-to-DC conversion manages the +3.3V and +5V rails for tighter regulation. Output voltage on +12V, +5V, and +3.3V rails remains stable under dynamic transient loading conditions, with exceptionally low ripple on the +12V rail. Protection features include over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-power protection (OPP), short-circuit protection (SCP), over-temperature protection (OTP), surge and inrush protection, and no-load operation support. The unit accepts full-range auto input voltage from 100V to 240V via active PFC, making it compatible across global power standards. It also complies with Energy Star and EuP regulations and is manufactured with RoHS/WEEE-compliant lead-free materials.
