The updated Seasonic CORE GX ATX 3.1 Series complies with the latest ATX 3.1 and PCIe 5.1 standards and includes four output ranges from 1000 W to 650W in both black and white colors. Catering to a broad spectrum of PC enthusiasts and system builders, these power supplies provide a fine balance between cost and performance. The 80 PLUS® Gold certified Seasonic’s Core GX line is a fully modular designequipped with black cables featuring abraided pattern. These power supplies are solid performersfor a large range of applications, wherea 120 mm Hydro Dynamic Bearing fanis combined with Seasonic’s Smart and Silent Fan Control to ensure the optimal cooling performance at the lowest possible noise level.
New Seasonic OptiSink™ Design
The overall quality and reliability of the new CORE GX ATX 3.1 Series has been greatly improved by a brand-new PCB (Printed Circuit Board) layout and the implementation of automated surface mount technology during production, which minimizes human production errors. By using a redesigned PCB combined with smaller MOSFET and heat sink components, the internal space within the power supply was increased to enhance heat dissipation and airflow to result in better component cooling.
Optimized for PCIe 5.1 GPUs
The CORE GX 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 600W 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.
