The Seasonic FOCUS GX-850 is an 850-watt power supply unit housed in a white chassis and designed for standard ATX systems. It complies with ATX 3.1 and PCIe 5.1 specifications, providing stable power delivery for current-generation processors and high-demand graphics cards. The unit's fully modular design simplifies installation and helps improve internal airflow by allowing for the use of only necessary cables. With a compact depth of 140mm, it offers enhanced compatibility with a wide range of ATX computer cases.
This PSU holds an 80 PLUS Gold certification, indicating up to 90% efficiency under typical operating loads, which reduces excess heat and energy consumption. Cooling is managed by a 135mm fan that incorporates a silent mode for quiet operation during low-power tasks. The inclusion of Active Power Factor Correction (PFC) and a comprehensive suite of protection circuits—including OVP, OPP, and SCP—contributes to consistent and safe system performance. Its internal components are rated for a mean time between failures (MTBF) of 100,000 hours.
