The Seasonic CORE GC-850W is an ATX power supply unit designed to provide 850 watts of continuous power for desktop systems. It is built to the ATX 3.1 standard, ensuring appropriate power delivery and connector support for current-generation hardware. With an 80 PLUS Gold certification, the unit operates with high energy efficiency, which helps reduce wasted heat and electricity consumption. The standard ATX dimensions, combined with a compact 140 mm depth, facilitate installation in a wide variety of computer chassis.
Thermal management is handled by a 120 mm fan featuring Smart and Silent Fan Control (S2FC), which modulates fan speed according to system load for quieter operation under light workloads. This model utilizes a non-modular design with fixed cables directly attached to the main unit. A complete suite of industrial-grade protections, such as Over Voltage Protection (OVP) and Short Circuit Protection (SCP), is integrated to safeguard connected components from electrical irregularities. The steel casing is coated with a scratch-resistant finish for increased durability.
