Napájací zdroj Lian Li SP Series Platinum SFX 850W plne modulárny PCIe 5.1 ATX 3.1 (G9P.SP0850P.B000.EU)

The Lian Li SP Series Platinum SFX 850W is a compact, high-efficiency power supply designed for small-form-factor and compact PC builds. Offering 850 watts of continuous output, fully modular cabling, PCIe 5.1 compatibility and ATX 3.1 support, this unit provides stable power delivery for modern CPUs and GPUs while minimising space and cable clutter. Its 80 PLUS Platinum efficiency ensures lower heat and reduced power loss under typical loads, making it suitable for high-performance gaming systems, content-creation workstations, and compact professional rigs.

Advantages

The fully modular design allows installation flexibility and improved airflow in tight cases by using only the cables required. PCIe 5.1 compatibility ensures support for the latest graphics cards and their higher power connector standards, while ATX 3.1 support provides up-to-date power delivery features for modern platforms. High efficiency (80 PLUS Platinum) and stable voltage regulation reduce system heat and improve overall reliability under load. The SFX form factor makes this PSU appropriate for compact builds without sacrificing power capacity.

Suitable for

• Small-form-factor gaming PCs with high-end graphics cards
• Compact workstations for photo, video or 3D rendering
• Mini-ITX systems where space and cable management are critical
• Systems requiring PCIe 5.1 power compatibility and ATX 3.1 features

Key specifications

• Form factor: SFX
• Continuous output power: 850 W
• Efficiency rating: 80 PLUS Platinum
• Cabling: Fully modular
• PCIe compatibility: PCIe 5.1 connectors supported
• Standard compliance: ATX 3.1
• Cooling: internal fan with thermal control (manufacturer-specified)

How to use

Install the power supply into a compatible SFX or supported compact chassis following the case and PSU installation instructions. Connect the fully modular cables only as needed: motherboard 24-pin, CPU 8-pin/4+4 power, and PCIe connectors for graphics cards according to the GPU manufacturer’s requirements. Ensure correct cable routing to maintain airflow and avoid sharp bends. Verify that the system ground and case mounting are secure before powering on the PC. Use a compatible power cord and a properly rated mains supply.

Recommendations

For reliable operation, select cables and connector combinations that match your components’ power requirements and follow manufacturer guidance for PCIe 5.1 GPUs. Maintain adequate case airflow and periodic dust removal to preserve efficiency and cooling performance. When pairing with very high-power GPUs or overclocked systems, confirm total system power draw remains within the 850 W continuous rating and allow some headroom for transient peaks.
