Product overview
Super Flower’s Leadex III 850W (Gold) is an ATX 3.1 refresh of the Leadex III family. The ATX 3.1 variant reached retail in October 2024 (Japan) and was Cybenetics‑certified on April 14, 2025, confirming the current spec.
Positioned as a high_end, fully modular 80 Plus Gold ATX unit, it exists to power modern single‑GPU builds without stepping up to 1 kW. Its 850 W capacity, ±1% voltage regulation, and ATX 3.1 excursion tolerance make it a solid choice for mid‑range gaming and high‑end GPU builds with a bit of headroom/overclocking. It supports PCIe Gen5 cards via a bundled dual‑8‑pin‑to‑12V‑2x6 cable (native 12V‑2x6 is reserved for 1000 W+ models). Not discontinued as of 2026.
