Product information

Description

The lian li SX Series 850W 80 PLUS Platinum fully modular power supply combines high-efficiency performance with modern compatibility for contemporary desktop systems. Delivering up to 850 watts of continuous power, this ATX 3.1 unit supports PCIe 5.1 graphics power requirements and is built to provide stable voltage rails, improved energy efficiency and tidy cable routing through a fully modular connector layout. It is intended for use in high-performance PCs and gaming rigs where reliable power delivery and compliance with the latest interface standards are required.

Advantages

This power supply offers an 80 PLUS Platinum efficiency rating to reduce wasted energy and lower system heat under typical loads. Full modularity simplifies installation and cable management by allowing only required cables to be connected, improving airflow inside the chassis. Native support for ATX 3.1 and PCIe 5.1 ensures compatibility with modern motherboards and next-generation graphics cards, while robust power delivery design maintains stable output for demanding components.

Suitable for

  • High-performance gaming PCs with modern graphics cards
  • Workstations for video editing, 3D rendering, and content creation
  • System upgrades that require PCIe 5.1 and ATX 3.1 compatibility
  • Compact builds that need efficient power delivery and modular cabling

Key specifications

  • Output power: 850 W continuous
  • Efficiency certification: 80 PLUS Platinum
  • Cabling: fully modular connector system
  • Standards supported: ATX 3.1 and PCIe 5.1 compatibility
  • Cooling: integrated fan with thermal management (model-dependent fan control)
  • Form factor: ATX (standard desktop power supply)

How to use

Install the power supply into an ATX-compatible case following the chassis manufacturers instructions, secure it with the provided screws and connect the required modular cables to the motherboard, CPU power input and graphics card. Ensure that PCIe 5.1 power connectors are used where the graphics card requires them, and route cables to avoid obstructing airflow. Verify all connections before powering on the system and monitor voltages and temperatures during the initial boot and stress testing to confirm stable operation.

Usage recommendations

For optimal reliability, pair the unit with components that match its power capacity and efficiency class, maintain adequate case airflow, and use the included modular cables rather than third-party adapters. Regularly check for firmware or BIOS updates from the system or motherboard manufacturer to ensure full compatibility with ATX 3.1 and PCIe 5.1 features.
