Seasonic CORE GX ATX 3.1 (SRP-CGX851-A5A32SF-W) 850W PSU

Seasonic Core GX-850-V2-WHITE ATX3.1

CORE GX White ATX 3.1
The updated Seasonic CORE GX White 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 PLUSGold 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.

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

Optimized for PCIe 5.1 GPUs
The CORE GX White 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.

Full Support for Legacy GPUs
To ensure compatibility with older GPUs, the CORE White GX ATX 3.1 includes a 12V-2x6 to 2x 8-pin PCIe adapter 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.

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.
