Product information

Description

The lian li SX Series 850W 80 PLUS Platinum is a fully modular ATX 3.1 power supply engineered to deliver stable continuous power for high-performance desktops and gaming systems. Designed with support for PCIe 5.1 devices, this 850W unit combines high conversion efficiency with a compact, build-friendly layout. Fully modular cabling and modern connectors simplify installation, improve airflow, and help maintain tidy cable management in small and full-sized chassis.

Advantages

High 80 PLUS Platinum efficiency reduces heat and power draw while ensuring reliable delivery of continuous 850W output for demanding components. The ATX 3.1 compliance and PCIe 5.1 compatibility provide future-ready connector support for the latest graphics cards and peripherals. Fully modular design lets builders attach only the cables they need, improving airflow and simplifying upgrades or maintenance. The unit is intended to deliver consistent voltage regulation and protection features suitable for gaming, content creation, and workstation builds.

Suitable for

  • High-performance gaming PCs with modern GPUs supporting PCIe 5.1
  • Compact and mid-tower builds requiring ATX 3.1 features and efficient cooling
  • Content creation systems with multi-drive and high-core-count CPU configurations
  • System upgrades where modular cabling and future connector compatibility are needed

Key specifications

  • Continuous power: 850 watts
  • Efficiency rating: 80 PLUS Platinum
  • Form factor and standard: ATX 3.1 compliant
  • GPU interface support: PCIe 5.1 compatible connectors
  • Cabling: fully modular cables to optimize build layout and airflow
  • Cooling: integrated fan with thermal control for quiet operation under varying loads
  • Protection features: over-voltage, under-voltage, over-current, short-circuit protections (built-in)

How to use

Install the power supply into an ATX-compatible chassis using the standard mounting points, orienting the unit to match the case airflow. Connect the 24-pin motherboard cable, CPU EPS connector(s), and the required PCIe connectors for the graphics card(s). Attach storage and peripheral power cables as needed from the modular cable set. Verify all connections are secure before powering on the system and configure BIOS/UEFI power settings as required for ATX 3.1 features. During first startup, monitor system voltages and temperatures to confirm stable operation.

Usage recommendations

For optimal performance and longevity, use high-quality modular cables as supplied, maintain case airflow by routing unused cables externally or storing them outside the main airflow path, and ensure your chassis supports the thermal requirements of an 850W unit. When installing high-power PCIe 5.1 GPUs, connect all recommended PCIe power connectors and check GPU vendor guidelines for power delivery. Regularly inspect connectors and clean dust from the intake and exhaust areas to sustain efficient cooling and reliable operation.
