Lian Li SX Series 1,000W power supply
The Lian Li SX Series 1,000 W reliably powers even high-end components. It supports current AMD and Intel processors as well as large graphics cards like the RTX 5000 series.

Thanks to ATX 3.1 and PCIe 5.1 compatibility, it is also well prepared for upcoming hardware generations. The power supply also offers a native 12V 2×6 connector for modern GPUs – completely without adapters.

High efficiency & quiet operation
Power supply with fan
Inside, high-quality Japanese capacitors ensure stable power delivery and long service life. With an efficiency of up to 92%, the power supply operates very energy-efficiently.

The 120 mm FDB fan runs at up to 2,000 RPM under heavy load, keeping temperatures cool. At low load, it automatically switches to Zero-RPM mode – for completely silent operation.

Clean cable management thanks to modular design
Fully modular power supply
The Lian Li SX Series offers fully modular connectors. You only connect the cables you actually need – keeping your system tidy and airflow unobstructed.

The included braided cables are flexible and easy to route. The 12V 2×6 connector features a two-color marking that indicates when the connector is securely latched. So you can be sure the plug is properly seated.

Safe & durable
For maximum safety, the power supply protects your system with multiple protection features such as overvoltage, overload, short circuit, and no-load protection. This keeps your hardware protected in the long term.
