Overview

An 850-watt fully modular ATX 3.1 power supply rated 80 PLUS Platinum. It supports PCIe 5.1 graphics cards with a native 12V-2x6 connector and includes a zero-RPM fan mode for silent low-load operation.

Design and Build

The unit measures 150 mm deep, 86 mm wide, and 140 mm high in a black finish. A 120 mm fluid dynamic bearing fan provides cooling and stops completely under light loads. Internal components include Japanese capacitors for stable voltage regulation and long service life.

Performance and Compatibility

Delivers 850 W total power with 849.6 W available on the single +12 V rail. Meets ATX 3.1 and PCIe 5.1 standards, supporting current AMD and Intel CPUs plus high-end GPUs such as the RTX 5000 series. The native 12V-2x6 connector eliminates the need for adapters.

Cable Management

Fully modular connectors let you install only the cables required. Included braided cables reach up to 700 mm for CPU and PCIe, 600 mm for the 24-pin and 12V-2x6, and 850 mm for SATA. The 12V-2x6 plug features a two-color indicator that confirms a secure lock.

Protections and Warranty

Safety circuits cover overcurrent, overvoltage, undervoltage, overload, short-circuit, and overtemperature conditions. The power supply is backed by a 10-year manufacturer warranty.
