850 W ATX 3.1 Platinum power supply

This fully modular unit delivers 850 W of continuous power with 80 PLUS Platinum and Cybenetics Platinum efficiency ratings. It meets the Intel ATX 3.1 specification and is PCIe 5.1 ready for modern graphics cards. The white finish suits clean, light-themed builds. It is built for enthusiasts who need stable output and high efficiency at typical loads.

Full modular ribbon cables with native 12VHPWR

All cables are detachable ribbon types, including two native 8-pin to 16-pin 12VHPWR leads that plug directly into the PSU without a 16-pin socket on the unit side. This reduces connection bulk and improves seating reliability. The 140 mm fluid dynamic bearing fan runs quietly under load. Standard ATX dimensions of 150 mm depth fit most mid-tower cases.

Single +12 V rail with 850 W headroom

The single-rail design provides the full 850 W on the +12 V line, handling high-end GPUs and multi-core CPUs with room for transient spikes allowed by ATX 3.1. Efficiency peaks at 92% at 50% load (115 V) and 93% at 50% load (230 V). Protection circuits include over-voltage and overload safeguards. Builds requiring more than 850 W or multiple 12VHPWR connectors will need a higher-capacity unit.

Questions about this item

How can I verify the SF-850F14XP(WH) is delivering stable power after installation?

The 140 mm Fluid Dynamic Bearing fan should spin quietly under load and the single +12 V rail will maintain steady voltage; efficiency reaches 90 % at 20 % load, 92 % at 50 % load and 89 % at 100 % load per 80 PLUS Platinum testing.

Which cables and connectors come in the box with the SF-850F14XP(WH) and what must I source separately?

All modular ribbon cables are included, among them a native 12 VHPWR cable built from two 8-pin leads to a 16-pin connector; no extra cables are required for standard ATX 3.1 builds.

Should I choose the white SF-850F14XP(WH) or a different capacity for an ATX 3.1 system with a PCIe 5.1 graphics card?

The white 850 W unit is ATX 3.1 certified and PCIe 5.1 ready, providing a native 12 VHPWR cable; select it when your peak draw fits within 850 W.
