Seasonic Focus GX-850-V4 850W

Reliable 850W ATX 3.1 Power Delivery — The Seasonic FOCUS GX-850 PSU complies with the latest ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with current generation components and high-power graphics cards. 80 PLUS Gold Efficiency — Certified 80 PLUS Gold performance delivers up to 90 % efficiency at typical loads, reducing wasted energy and heat output for efficient system operation. Fully Modular for Clean Builds — Fully detachable cables allow custom cable management, reducing clutter and improving airflow inside your PC build. Quiet Digital Hybrid Fan Control — Features an advanced hybrid fan control system that transitions between fanless, silent, and cooling modes for near-silent operation during light loads and efficient cooling under heavy load. Compact & Durable Design — With a 140 mm length, fluid-dynamic bearing fan, and OptiSink internal design for improved heat dissipation, this PSU combines reliability with performance in compact chassis configurations.

Providing efficient power Following the well-established legacy of the Seasonic FOCUS Series, the FOCUS GX 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-2×6 cable, and new OptiSink technology. These units are designed to be perfect allies in powering the latest high-power graphics cards and processors available on the market. Silence and cooling, balanced The industrys 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. Streamlined airflow The overall quality and reliability of the FOCUS 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.

The newly upgraded FOCUS PX and GX series are the successors to the FOCUS PLUS Series. which became an instant top seller in the power supply market after its launch in 2017. In 2019. Seasonic engineers have made improvements to the popular series such as removing the inline capacitors on the supplied cables. Besides the small change in the series naming. the PSU housing and its packaging are also updated to be in line with the concept of the OneSeasonic Initiative.S3FC - Fanless until 30 % loadThe industry’s first. Seasonic patented. advanced three-phased thermal control achieves optimal between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode. Silent Mode. and Cooling Mode.Fluid Dynamic Fan BearingHigh performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless. quieter rotations and its robust construction. this reliable fan technology also greatly increases the lifespan of the fan.When the fan shaft rotates. high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces.As the speed increases. so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth. effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.
