Leadex III ATX 3.1 1000W

The Super Flower Leadex III SF-1000F14GE delivers 1000W through a fully modular ATX 3.1 design. It targets builders who need stable power for high-end graphics cards and multi-drive arrays. The unit carries 80 PLUS Gold and Cybenetics Platinum certifications. A native 12V-2x6 connector supports modern GPU requirements.

Sustained load behaviour

Efficiency reaches 90% at 50% load and 87% at both 20% and 100% rated load. Active PFC maintains power factor across the 100-240V input range. The single +12V rail supplies the full 1000W without rail balancing. Protection circuits include OVP, OCP, OPP, SCP, UVP, OTP, NLO and SIP for continuous operation.

Build and daily use

A 140mm fluid dynamic bearing fan with copper shaft runs in semi-fanless ECO mode at low loads. Full modular cabling uses ribbon-style wires for cleaner routing inside the case. The 150mm chassis depth fits standard ATX bays. Eight SATA connectors and four 8-pin PCIe plugs handle dense storage and multi-GPU layouts.
