01DESKTOPS & ACCESSORIES

Silent precision for the modern build

Tucked away in the rear of your case, this white unit blends into the aesthetic while handling the heavy lifting. Its low-profile design respects the spatial constraints of modern PC builds without sacrificing headroom.

The Seasonic FOCUS GX-850 provides stable, efficient power for high-performance components. It suits builders who value quiet operation and clean cable management as much as raw output.

02DESIGN

Compact form factor for tight spaces

At just 140 millimetres deep, this unit slips into cases where standard ATX power supplies feel cramped. The white shroud matches light-themed builds, offering a cohesive visual line from motherboard to drive cage. This reduced depth allows for better airflow clearance around the CPU cooler.

04DETAILS

Modular cabling and robust protection

Flat, fully modular cables allow for tidy routing through any case layout, reducing clutter behind the motherboard tray. Gold-plated connectors provide reliable contact points, while comprehensive protections like OVP and SCP safeguard components from electrical spikes. The fluid dynamic bearing ensures the fan lasts for fifty thousand hours under typical conditions.
