01DESKTOPS & ACCESSORIES
Quiet power for the modern build
Tucked away in the chassis, this unit provides the steady current that keeps your components humming without intrusion. Its compact form factor integrates seamlessly into high-end desktop builds, prioritising order and silence over visual spectacle.
The Seasonic Core GX-850 suits builders seeking reliable performance from a full-range AC input. It delivers consistent power through its fully modular connectivity, ensuring cable management remains tidy and efficient within the case.
02DESIGN
Modular architecture for cleaner routing
The unit adopts a fully modular layout, allowing you to connect only the necessary cables. This approach reduces clutter inside the chassis and improves airflow around critical components. The individual black cables feature a braided pattern, adding a tactile texture that complements the sleek exterior while maintaining flexibility during installation.
04ACOUSTICS
Fluid dynamics for silent cooling
A 120 mm fan equipped with a fluid dynamic bearing drives the cooling process. Paired with Seasonic’s Smart and Silent Fan Control, the system adjusts speed dynamically to match thermal loads. This results in optimal airflow at the lowest possible noise level, keeping the background hum barely perceptible during intensive tasks.
05DURABILITY
Built for long-term reliability
With an MTBF of 100,000 hours excluding the fan, the internal electronics are designed for longevity. The fan itself is rated for 25,000 hours under specific humidity conditions. Comprehensive protection circuits guard against overcurrent, overvoltage, and short circuits, safeguarding the connected hardware from electrical anomalies.
