## Long description

The Seasonic Focus GX 850 W is a compact ATX power supply unit delivering 850 W of continuous power for desktop PCs. It is 80 PLUS Gold certified for high efficiency and accepts 100–240 V AC input at 50/60 Hz. The unit comes with a 20+4 pin ATX motherboard connector and a full set of cables including CPU, PCIe, SATA and Molex adapters. Cooling is handled by a 120 mm fan with Seasonic’s hybrid thermal control that provides fanless operation up to light loads and automatic silent or cooling modes as required.
Advantages
The Focus GX 850 W combines high efficiency (80 PLUS Gold) with a robust 850 W output suited to demanding systems. Seasonic’s S3FC three-phased thermal control enables fanless operation at low loads and switches smoothly between Fanless, Silent and Cooling modes for quiet, reliable performance. A high-quality Fluid Dynamic Bearing (FDB) fan reduces noise and improves lifespan compared with ball-bearing designs. The PSU is supplied with a complete set of cables and a 20+4 pin ATX connector, with cable lengths suitable for typical mid-tower and full-tower builds.
Suitable for
High-performance gaming PCs and workstations requiring up to 850 W
Systems where efficiency and low noise are priorities
Mid-tower and full-tower desktop builds using standard ATX wiring

How to use
Install the Seasonic Focus GX 850 W into a standard ATX PSU bay following your case manufacturer’s instructions. Connect the 20+4 ATX main connector to the motherboard, then attach the CPU 4/8-pin, PCIe and SATA/Molex cables to the corresponding components. Ensure AC mains voltage is within 100–240 V and use the supplied power cable. For optimal airflow, position the fan intake according to your case layout and route cables to avoid obstructing airflow.
Usage recommendations
For quiet operation, allow the hybrid S3FC control to manage the fan automatically; the unit remains fanless under light load (up to approximately 30% load) and engages silent or cooling modes as system demand increases. Periodically check and clean vents and the fan to maintain cooling efficiency.
