The Lian Li SX Series 1 200 W power supply is the perfect choice for anyone who wants to build a high-performance gamer PC or workstation. The power of up to 1,200 watts is enough to drive high-end processors, modern video cards and serious cooling systems.
The 120mm fan operates quietly in Zero RPM mode when the system is running at low load. The fully modular design results in a tidy interior - you only connect the cables you really need.

- 1,200 watt power: ideal for a PC equipped with high-end hardware
- 80 PLUS Platinum efficiency: up to 92% efficiency at half load
- Fully modular: with flexible, stocking cables
- ATX 3.1 & PCIe 5.1 standard: future-proof, modern GPU compatibility
- Quiet operation: 120 mm fan with Zero RPM mode

Lian Li SX Platinum: maximum performance for modern hardware
The Lian Li SX Series 1,200 W easily supplies even the most demanding components with energy. It supports up-to-date AMD and Intel processors, as well as large graphics cards - such as the RTX 5000 series.
Thanks to ATX 3.1 and PCIe 5.1 compatibility, it also serves the hardware generations of the near future. With the native 12V 2x6 connector, it can also be connected to modern GPUs without an adapter.

High efficiency & quiet operation
High-quality Japanese capacitors guarantee a stable power supply and a long service life. Its efficiency is up to 92%, so it offers an energy-saving solution. The 120 mm FDB fan spins up to 2,000 rpm at high load, but switches to Zero RPM mode at low load, so the operation is completely silent.

Orderly cabling thanks to the modular system
The Lian Li SX Series works with fully modular connectors. You only use the cables you really need - so the inside of the house is always tidy and the air can flow freely.
The included stocking cables are flexible and easy to route. The 12V 2x6 connector is two-colored, so it is clearly visible when the connection is properly closed.

Safe & durable
Maximum safety is ensured by multiple protection functions, including over-voltage, overload, over-temperature, short-circuit and under-load protection. This way, your hardware remains safe in the long term.
