Description

CORE BC – Power Made Simple

The Seasonic CORE BC Series delivers reliable performance and modern ATX 3.1 compliance at an essential value. Designed for everyday builders and gamers, it embodies Seasonic’s trusted quality in a compact 140 mm design with a durable scratch-resistant finish.

With 80 PLUS® Bronze efficiency, Smart and Silent Fan Control (S2FC), and a 120 mm HDB fan, it ensures cool, quiet, and stable operation. The CORE BC-750 and CORE BC-850 include a 12V-2×6 PCIe Gen 5.1 cable, ready for the latest GPUs, while the CORE BC-650 meets all ATX 3.1 requirements with traditional connectors.

Built on decades of engineering excellence, the CORE BC Series delivers the quiet efficiency, reliability, and durability that define every Seasonic power supply.

Next-Gen and Legacy GPU Cable
Includes native 12V-2x6 and 2× 8-pin cables for maximum compatibility

S2FC - Intelligent Fan Control Technology
The Smart and Silent Fan Control (S2FC) system intelligently regulates the power supply’s fan speed to achieve the ideal balance between cooling efficiency and silent operation. By dynamically adjusting the fan curve according to temperature, it ensures that your system remains quiet during low-to-medium usage and effectively cooled when performance demands increase.
