The Seasonic CORE BC-850W is an ATX power supply unit designed to deliver 850 watts of continuous power. It adheres to the ATX 3.1 standard, ensuring compatibility with current and next-generation component specifications. The unit features an 80 PLUS Bronze certification for electrical efficiency. Included is a native 12V-2x6 PCIe 5.1 cable, which directly supports modern high-performance graphics cards without the need for adapters. Its non-modular, fixed cable design provides a direct connection for all components.
This power supply is built into a compact 140 mm deep chassis, making it suitable for a wide range of ATX-compatible computer cases. Thermal management is handled by a 120 mm Hydro Dynamic Bearing (HDB) fan, which is regulated by Seasonic's Smart and Silent Fan Control (S2FC) system. This technology adjusts fan speed in response to system load to balance cooling performance and acoustic output. The unit is also equipped with a standard set of protection circuits, including OVP, UVP, OPP, OCP, OTP, and SCP, to safeguard system components.
