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 White line is a fully modular design equipped with white 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 White 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.

Fully Modular Cables

In Sea Sonic's patented design feature full modularity comes hand-in-hand with the extensive use of SMD technology to increase the overall performance and reliability of this power supply. The simple and inventive layout scheme helps to attain unsurpassed quality and performance, where efficiency is further enhanced by minimized line resistance, reduced voltage drop and lower impedance. Reduced component count and better space utilization facilitate optimal air flow inside the case and promote heat dissipation, proper cooling and ultimately longer product life.

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.

Cables Included

Recommended 12V-2x6 Cable Installation

- Your 12V-2x6 cable must be connected with one end to the PSU and the other end to your GPU.
- For safety and stability, ensure both connectors are fully INSERTED, CLICK-LOCKED, and TIGHT before powering on your system.
- DO NOT bend or apply force to the cable after it is plugged into place.
