Power Supply LIAN-LI SX1000P 80 Plus Platinum 1000W

Lian Li SX Platinum

Platinum-grade power — quietness, stability, and uncompromising reliability.

High-efficiency Platinum certification

The SX Platinum series delivers an advanced performance experience with 80 PLUS® Platinum and PPLP Platinum standards, and full compatibility with ATX 3.1 and PCIe 5.1 — perfect for building modern high-performance systems.

A stable single +12V rail, fanless quiet operation up to 40% load, and high-quality Japanese components to extend product lifespan and long-term durability — so you can rely on the system in any scenario.

Smart Stop/Start for absolute silence at low loads

At loads of 40% and below, the Smart Stop mechanism turns the fan off completely to maintain absolute silence during everyday work, streaming, or office use.

You can enable or disable the function with a dedicated switch on the back of the PSU, giving you full control between silent mode and continuous cooling as needed.

Full modularity for a clean, efficient layout

A fully modular design lets you connect only the cables you actually need, improving airflow, easing maintenance, and delivering a clean, aesthetic look for a showcase-ready build.

Full support for ATX 3.1 and PCIe 5.1

Support for load spikes up to 200% of the rated output ensures stable power delivery even under extreme peaks, making it especially suitable for next-generation graphics cards and heavy gaming and content creation systems.

Comprehensive protection array to ensure reliability

A comprehensive protection system including OCP, OVP, OTP, OPP, SCP, UVP, NLP, and SIP — protecting against overcurrent, overvoltage, overheating, overload, short circuit, and abnormal fluctuations.

This keeps your valuable PC components safe and ensures stability even under sustained load.
