Seasonic launches the updated CORE ATX 3 Series

The updated Seasonic series is a well-established member of Seasonic’s comprehensive product lineup, catering to a broad spectrum of PC enthusiasts and system builders. Following the newest trends in graphics card design, the units in this family comply with the latest ATX 3.1 and PCIe Gen 5.1 standards.

The CORE GX ATX 3 series can be purchased in four output variants, ranging from 1000 W to 650 W, in both black and white colors. Aiming for easy installation and clutter-free cable management, these 80 PLUS® Gold certified units of the Seasonic’s CORE GX family follow a fully modular design equipped with color-matching cables featuring a braided pattern.

Built with the well-recognized Seasonic quality, these power supplies are solid performers for a large range of applications. 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 emission level. The Seasonic CORE GX ATX3 power supplies are backed by Sea Sonic’s 7-year worldwide manufacturer’s warranty.

The overall quality and reliability of the new CORE GX ATX 3 Series has been greatly improved by a brand-new PCB (Printed Circuit Board) layout. 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 CORE ATX 3 power supply supports a native 12V-2×6 16-Pin connector and up to three CPU/GPU 8-Pin connectors to meet the diverse power demands of various systems.
