Overview


CORE GX ATX 3.1
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 650?W 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 design equipped with black cables featuring a braided pattern. These power supplies are solid performers for a large range of applications, where a 120 mm Hydro Dynamic Bearing fan is combined with Seasonic’s Smart and Silent Fan Control to ensure the optimal cooling performance at the lowest possible noise level. These quality power supplies are backed up by Sea Sonic’s 7-year worldwide manufacturer’s warranty.

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.

The eightfold increase in heat dissipation keeps the internals of the power supply cooler, eventually leading to improved product quality, long-term reliability, and more efficient operation.

The redesigned layout of the power supply components and its improved thermal performance creates versatility and allows the power supply to be safely installed in any orientation.

The OptiSink design is an eco-friendly solution that not only lowers the costs of material usage and production but also leads to energy savings in the long run.

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

S2FC - Smart And Silent Fan Control
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
