01ELECTRIC HEATERS
Silent power for compact builds
Tucked into the corner of a compact case, this unit remains largely unseen yet essential. Its low-profile design respects the spatial constraints of small-form-factor systems without compromising on electrical headroom.
The Seasonic FOCUS SPX-750 delivers 750 watts of continuous power with Platinum-level efficiency. It suits builders prioritising silence, clean cable management and long-term reliability in high-performance desktops.


02DESIGN
Compact footprint with expandability
Measuring 125mm in length, 100mm in width and 63.5mm in height, the SFX form factor fits where standard ATX units cannot. The design allows for easy expansion to larger cases if your build evolves, maintaining compatibility while preserving the sleek, contained aesthetic of a modern PC interior.

04DETAILS
Modular cabling and robust protection
Flat black cables are fully modular, allowing you to connect only what is needed for a tidy interior. Gold-plated connectors ensure reliable signal transmission, while comprehensive protections including over-voltage, under-voltage and short-circuit safeguards guard your components. The unit handles full-range AC input from 100V to 240V.
