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.

- Fully compliant with PCIe 5.1 and ATX 3.1 standards
- Up to 600W of power
- The CORE GC-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 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.

- Ideal for graphics cards from previous generations
- Easy to install for users upgrading from older systems
