Seasonic B12 BC 850W - PSU, 80 Plus Bronze

The Seasonic B12 BC 850W is a power supply unit designed for standard ATX-compatible systems, delivering a nominal power output of 850 watts. It features an 80 PLUS Bronze certification, indicating an efficiency of up to 85% under typical load conditions. The unit employs an LLC resonant converter design to ensure stable voltage regulation and reliable power delivery to all components. Its non-modular configuration utilizes fixed, flat black cables for direct connection to the motherboard and peripherals.

For thermal management, the PSU is equipped with a 120mm fan governed by Seasonic's Smart and Silent Fan Control (S2FC) system. This technology adjusts the fan's rotational speed in response to the system's power draw, balancing cooling performance with acoustic output. The unit also integrates a suite of essential protection circuits, including Over Power (OPP), Over Voltage (OVP), Over Current (OCP), and Short Circuit (SCP) protections to safeguard connected hardware.
