Seasonic SRP-CGX851-A5A32SF PC power supply unit 850 W ATX, EPS 80 PLUS Gold

CORE GX ATX 3 (2024)
The updated Seasonic CORE GX ATX3 series complies with the latest ATX3 standards and includes four power ranges from 1000W to 650W in black and white. Catering to a wide range of PC enthusiasts and system developers, these power supplies offer a good balance between cost and performance.The 80 PLUS®Gold certified Seasonic's Kern GX line is a fully modular design equipped with black cables with a mugged pattern. These power supplies are solid performance carriers for a large range of applications, where a 120 mm fluid-dynamic fan is combined with Seasonic's Smart and silent fan control in order to ensure the optimum cooling power at the lowest noise level.

ATX 3.1 and 16-pin PCIe Gen 5 cable (12V-2x6)
SeasonicThe latest series CORE GX ATX 3 was developed and built for power supply of new PC components that require the new standards ATX 3.1 and PCIe 5.1.

Fully modular cable
The patented design of Sea Sonicis fully modularity goes hand in hand with the extensive use of SMD technology in order to enhance the total power and reliability of this power supply. The simple and original layout scheme contributes to unsurpassed quality and performance, while further improving efficiency with minimized line resistance, lower voltage drop and lower impedance. A reduced number of components and a better use of the space allow optimum air circulation in the housing and promote heat dissipation, adequate cooling and ultimately a longer life of the product.

New Seasonic optical sink design
The overall quality and reliability of the new CORE GXATX 3 series has been significantly improved thanks to a brand new PCB layout (printed circuit board) and the introduction of automated surface mounting technology during production, which minimizes human production errors.



Using a redesigned PCB in combination with smaller MOSFET and heatsink components WAS, the internal space of the power supply has been increased to improve heat dissipation and airflow, leading to better cooling of the components.

Increase thermal conductivity
The eight-fold increase in heat dissipation keeps the inside of the power supply cooler, and WAS ultimately leads to improved product quality, long-term reliability and more efficient operation.

The newly designed layout of the power supply components and the improved thermal performance provide versatility and enable a safe installation of the power supply in every orientation.

The OptiSink design is an environmentally friendly solution that not only reduces the cost of materials and production, but also saves energy in the long term.

S2FC intelligent and quiet fan control
The intelligent thermal circuit was developed to find the optimum balance between the need to cool the components and the need to operate the power supply as quietly as possible.
