SEASONIC FOCUS GX ATX 3 (FOCUS-GX-850-V4)

ATX 3.1 and 16-Pin PCIe Gen 5 Cable (12V-2x6)
Seasonic’s latest FOCUS 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


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.

Increase Thermal Conductivity
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.
