Seasonic Focus GX-850 V4 ATX 3.1 850W 80 Plus Gold White ATX Power Supply

FOCUS GX White ATX 3.1

Following the well-established legacy of the Seasonic FOCUS Series, the FOCUS GX White Series has been upgraded to comply with the ATX 3.1 and PCIe 5.1 standards. It offers a complete range of power supplies from 750W to 1000W, all within a compact 140mm depth. Each unit features a 135mm fan, a 12V-2x6 cable, our new OptiSink technology and a stunning white finish. These units are designed to be perfect allies in powering the latest high-power graphics cards and processors available on the market.

New Seasonic OptiSink Design

The overall quality and reliability of the FOCUS v4 Series has been greatly improved by a brand-new PCB (Printed Circuit Board) layout and the implementation of automated surface mount technology during production, which minimizes human production errors.

By using a redesigned PCB combined with smaller MOSFET and heat sink components, the internal space within the power supply was increased to enhance heat dissipation and airflow to result in better component cooling.

The eightfold increase in heat dissipation keeps the internals of the power supply cooler, eventually leading to improved product quality, long-term reliability, and more efficient operation.

The redesigned layout of the power supply components and its improved thermal performance creates versatility and allows the power supply to be safely installed in any orientation.

The OptiSink design is an eco-friendly solution that not only lowers the costs of material usage and production but also leads to energy savings in the long run.

ATX 3.1 and 16-Pin PCIe Gen 5 Cable (12V-2x6)

Seasonic's latest FOCUS GX White ATX 3 Series is designed and built to power new PC components requiring the new ATX 3.1 and PCIe 5.1 standards.

Digital Hybrid Fan Control

The industry's first, Seasonic patented, advanced three-phased thermal control achieves optimal between silence and cooling. This Digital Hybrid Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode.

- Reduced noise without increase in temperature
- Extended fan life due to the reduced number of fan rotations
- Optimal heat dissipation ensured at all times, further enhanced with OptiSink technology.
- Unsurpassed silent performance in Fanless Mode

Cables Included

Recommended 12V-2x6 Cable Installation

- Your 12V-2x6 cable must be connected with one end to the PSU and the other end to your GPU.
- For safety and stability, ensure both connectors are fully INSERTED, CLICK-LOCKED, and TIGHT before powering on your system.
- DO NOT bend or apply force to the cable after it is plugged into place.
