Power supply 850W / Seasonic Focus GX GX-850-ATX31, APFC, Gold, PCIe5

Seasonic Focus GX-850W

Following the well-established Seasonic FOCUS series, the FOCUS GX series has been updated to meet ATX 3.1 and PCIe 5.1 standards. It offers a full range of power supplies from 750W to 1000W, each with a compact 140mm depth. Each unit features a 135mm fan, 12V-2x6 cable and our new OptiSink technology. These units are designed to be the perfect power assistants for the latest powerful graphics cards and processors on the market.

New Seasonic OptiSink design
The overall quality and reliability of the new Seasonic FOCUS series have been greatly improved by using a completely new printed circuit board (PCB) layout and the introduction of automated surface mount technology in the manufacturing process, minimizing human error during production. By utilizing a redesigned PCB combined with smaller MOSFET components and heat sinks, the internal space inside the power supply has been increased to improve heat dissipation and airflow, resulting in better component cooling. The eight-fold increase in heat dissipation keeps the internal components of the power supply cooler, ultimately resulting in improved product quality, long-term reliability and performance. The power supply's redesigned component layout and improved thermal performance provide versatility and allow the power supply to be safely installed in any orientation. The OptiSink design is an environmentally friendly solution that not only reduces material and manufacturing costs, but also results in long-term energy savings.

ATX 3.1 and 16-pin PCIe Gen 5 cable (12V-2x6)
Seasonic's latest Seasonic FOCUS series is designed and built to power new PC components that require the new ATX 3.1 and PCIe 5.1 standards.

Fully modular cables
Sea Sonic's patented design combines full modularity with extensive use of SMD technology to enhance the overall performance and reliability of this power supply. The simple and ingenious layout helps achieve unmatched quality and performance, where efficiency is further enhanced by minimizing line resistance, reducing voltage drop and lowering impedance. Reduced component count and better space utilization contribute to optimal airflow within the enclosure, heat dissipation, proper cooling and ultimately longer product life.

Digital Hybrid Fan Control
Seasonic's industry-first patented advanced three-phase thermal control allows for an optimal balance between silence and cooling. The digital hybrid fan control operates in three modes: Fanless Mode, Silent Mode, and Cooling Mode.
