Product Description
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.
The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill.
The CORE BC-650 complies with ATX 3.1 specifications but is supplied with traditional PCIe connectors instead of a 12V-2x6 cable. To ensure compatibility with older GPUs, the CORE BC ATX 3.1 includes a 2× 8-pin PCIe cable. It delivers reliable power up and works seamlessly with graphics cards from previous generations. This cable makes it easy to upgrade your PSU without changing your GPU—perfect for users who want next-gen power with legacy support.
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.
