Features
Focus GX White ATX 3 (2024) 850W
The New Centre of Attention
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.
80 Plus® Gold
The FOCUS GX White ATX 3 Series achieves 80 PLUS® Gold certification with its 90 % efficiency at 50 % system load.
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 minimises 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.
