The Seasonic Focus GX-850 is a power supply unit that provides a total output of 850 watts in a standard ATX form factor. It features an 80 PLUS Gold certification, indicating up to 90% operational efficiency, which helps reduce waste heat and energy usage. Its fully modular design permits the connection of only essential cables, contributing to cleaner system builds and unobstructed internal airflow. The unit's 140 mm depth allows for installation in a broad range of ATX-compatible computer cases.
A 120 mm fan with Hybrid Silent Fan Control handles thermal management. This system keeps the fan inactive under light loads up to 30% of the unit's capacity, resulting in silent operation for less demanding tasks. For component safety, the PSU is equipped with a comprehensive set of protections, including Over Power, Over Voltage, and Short Circuit Protection. Reliability is supported by active Power Factor Correction and a Mean Time Between Failures (MTBF) rating of 100,000 hours.
