SEASONIC power source Core GC-850 / 850W / ATX3.1 / 120mm fan / 80PLUS Gold

Powerful 850W power supply with the latest ATX 3.1 and PCIe 5.1 standards for modern gaming builds.

The SEASONIC Core GC-850 is a reliable solution for power users and gamers who need compatibility with the latest graphics cards. With full support for ATX 3.1 and PCIe 5.1 standards, it is ready for NVIDIA RTX 40 and future 50 series, while maintaining compatibility with older GPUs via traditional connectors.

With 80 PLUS Gold certification, it achieves high energy efficiency, which means lower power consumption and less heat loss. The compact dimensions of 140 × 150 × 86 mm and advanced S2FC fan control ensure quiet operation while maintaining optimal cooling.

Advanced cooling and fan control
The S2FC system intelligently adjusts the speed of the 120mm hydrodynamic bearing fan according to the current temperature and load. It ensures near-silent operation at low to medium loads, while providing effective cooling at higher loads.

Universal connectivity
The power supply offers a 24-pin motherboard connector, two 8/4-pin CPU connectors, three SATA connectors and a special 12V-2x6 cable for the latest graphics cards. All cables are firmly connected with high-quality braiding.

Reliability and safety
A complete set of protection functions protects connected components against overload, overvoltage, undervoltage, short circuit and overheating. An MTBF of 100,000 hours at 25°C guarantees long-term reliability.
