Overview

A fully modular 850W ATX 3.1 power supply with 80 PLUS Gold efficiency, a native 12V-2x6 connector for modern GPUs, and a compact 150mm depth. Ideal for mid-range to high-end gaming builds.

Design and Build

The unit measures 150mm long, 150mm wide, and 86mm high, allowing it to fit in compact ATX cases. A fully modular interface lets you connect only the cables required for your build. Flat, flexible cables simplify routing and improve airflow inside the chassis.

Performance and Efficiency

The single +12V rail delivers up to 849.6W of the total 850W capacity. 80 PLUS Gold and Cybenetics Gold ratings ensure high efficiency at typical loads, reducing heat output. The 135mm fluid dynamic bearing fan supports a semi-passive mode for silent operation under light loads, while achieving a Cybenetics A+ noise rating.

Connectivity and Compatibility

Native ATX 3.1 and PCIe 5.1 support includes one 12V-2x6 connector rated for 600W, eliminating the need for adapters with modern graphics cards. Additional connectors include two CPU power ports (4+4-pin and 8-pin), two 6+2-pin PCIe, eight SATA, and three Molex. The platform handles transient power spikes common in demanding workloads.

Protection Features

Integrated safety circuits cover overcurrent, overvoltage, undervoltage, overload, overtemperature, short-circuit, no-load, and surge protection. These safeguards help protect connected components during unexpected electrical events.
