Seasonic Core GC-750 ATX3
CORE GC – Power Made Simple
The Seasonic CORE GC 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 Gold efficiency, Smart and Silent Fan Control (S2FC), and a 120 mm HDB fan, it ensures cool, quiet, and stable operation. The CORE GC-750 and CORE GC-850 include a 12V-2×6 PCIe Gen 5.1 cable, ready for the latest GPUs, while the CORE GC-650 meets all ATX 3.1 requirements with traditional connectors. Built on decades of engineering excellence, the CORE GC 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 2x 8-pin cables for maximum compatibility
Optimized for PCIe 5.1 GPUs
The CORE GC ATX 3.1 power supply features a native 12V-2x6 cable designed for the latest PCIe 5.1 graphics cards. With support for up to 600 W of power delivery, this cable ensures safe and stable performance for NVIDIA RTX 40 and 50 Series and future high-end GPUs. Enjoy a clean, efficient setup that’s fully compliant with ATX 3.1 and PCIe 5.1 standards.
Full Support for Legacy GPUs
To ensure compatibility with older GPUs, the CORE GC 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.
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.
