Description
The Lian Li SX-P series represents a significant leap in power delivery, specifically engineered to meet the rigorous demands of modern high-performance computing. By integrating the ATX 3.1 standard and a dedicated 12V-2x6 connector, these units provide up to 200% power excursion support, ensuring that even the most power-hungry GPUs remain stable during peak loads. Available in 850W, 1000W, and 1200W variants, this series combines a compact 140mm depth with 80 PLUS Platinum efficiency, making it a versatile cornerstone for any premium PC build.
This product is for:
- High-End Gamers: Those utilizing NVIDIA RTX 40-series or 50-series cards who require the native 12V-2x6 power connection for maximum safety and performance.
- Compact Build Enthusiasts: Users with mid-tower or smaller cases who benefit from the 140mm short-chassis design, which frees up valuable space for cable management.
- Professional Content Creators: Editors and 3D artists who need the 80 PLUS Platinum efficiency to reduce heat and electricity costs during long rendering sessions.
- Silent PC Builders: Individuals who prioritize a quiet environment, utilizing the intelligent 0dB fan mode that stays silent under 40% load.
- Long-Term System Architects: Builders looking for a reliable component backed by a 10-year warranty and 100% Japanese industrial-grade capacitors.

Operating the SX-P series is a study in refined engineering. The fully modular design allows for a clean aesthetic, while the flexible cables simplify the routing process in tight corners. During low-to-medium intensity tasks, the power supply remains completely silent as the fan only engages once the load exceeds 40%. When the fan does spin up, the Fluid Dynamic Bearing ensures a smooth, low-frequency hum rather than a distracting whine, maintaining a premium acoustic profile even under heavy gaming loads.
Compared to traditional 160mm or 180mm high-wattage power supplies, the Lian Li SX-P series offers a distinct advantage in compatibility without sacrificing thermal headroom. While many Gold-rated units struggle with heat at high loads, the Platinum-rated efficiency of the SX-P ensures less energy is wasted as heat, allowing the unit to run cooler and quieter. Furthermore, the inclusion of the ATX 3.1 standard provides a more secure and robust power connection than the older ATX 3.0 or 2.0 standards, specifically addressing the thermal concerns associated with high-power GPU connectors.
Q&A:
- What is the benefit of ATX 3.1 over older standards? ATX 3.1 introduces the refined 12V-2x6 connector, which offers better physical engagement and thermal management for high-wattage graphics cards compared to the original 12VHPWR design.
- Does this power supply support the latest NVIDIA GPUs? Yes, the SX-P series is fully compatible with PCIe 5.1 and includes the necessary cables for direct connection to modern high-end GPUs without adapters.
- How does the fan-stop mode work? The intelligent fan control keeps the 120mm FDB fan stationary until the system load reaches approximately 40%, ensuring silent operation during web browsing or light office work.
- Are the internal components high quality? Lian Li utilizes 100% Japanese capacitors from top-tier manufacturers like Rubycon and Nichicon, rated for 105°C to ensure maximum longevity.
- What is the warranty period for the SX-P series? This power supply is backed by a comprehensive 10-year warranty, covering parts and labor to guarantee long-term system stability.
