Product information

Description

This Lian Li SX Series 80 PLUS Platinum fully modular power supply delivers 1,200 W of continuous power and complies with ATX 3.1 and PCIe 5.1 standards for modern desktop systems. Designed for high-performance builds, the unit provides efficient power conversion and a selection of modern connectors to support current-generation GPUs and CPUs while enabling tidy cable routing through its fully modular design.

Advantages

The 80 PLUS Platinum certification ensures high efficiency across typical load ranges, reducing heat generation and lowering energy costs compared with lower-efficiency units. Full modularity allows users to attach only the cables they need, simplifying installation and improving internal airflow. Compliance with ATX 3.1 and PCIe 5.1 provides compatibility with the latest power delivery requirements for GPUs and motherboards. The 1,200 W output supports multi-GPU configurations and high-core-count CPUs without compromising stability.

Suitable for

  • High-end gaming PCs with modern GPUs
  • Workstations for 3D rendering, video editing, and scientific computing
  • Overclocked systems and multi-GPU builds
  • PC builds requiring PCIe 5.1 and ATX 3.1 compatibility

Key specifications

  • Rated output: 1,200 W continuous
  • Efficiency: 80 PLUS Platinum
  • Form factor compatibility: ATX 3.1
  • PCIe support: PCIe 5.1 compatible connectors
  • Cabling: fully modular cable system for simplified routing
  • Cooling: fan-assisted cooling with thermal management (manufacturer-defined profile)

How to use

Install the power supply into a compatible ATX case following standard safety procedures: switch off and unplug the system, position the unit with correct airflow orientation, and secure it with screws. Connect the required modular cables to the PSU first, then to the motherboard, CPU, GPU(s), storage devices and peripherals, ensuring connectors are fully seated. Verify all voltage settings and power connections before powering on the system. Allow the PSU to run under moderate load initially to confirm stable operation and proper fan behavior.

Usage recommendations

For long-term reliability, maintain good case airflow and periodic dust cleaning. Use only required modular cables to reduce clutter and improve cooling. Ensure your build components are compatible with ATX 3.1 and PCIe 5.1 power requirements; consult component documentation when pairing with next-generation GPUs or power-hungry CPUs.
