Compact SFX Form Factor with Broad Compatibility
The Lian Li SP850P delivers professional-grade power in a compact 125 x 63.5 x 100 mm SFX form factor, making it ideal for small form factor builds. The included SFX-to-ATX bracket extends compatibility to mid-size and full-size cases, providing flexibility for various system configurations. Built with 100% Japanese Rubycon 105°C capacitors and engineered for reliability, this PSU maintains stable full output even at 40°C ambient temperatures.
80 Plus Platinum Efficiency with Smart Cooling
Certified 80 Plus Platinum with up to 92% efficiency at 50% load, the SP850P delivers cooler operation, quieter acoustics, and lower energy costs. The intelligent fanless mode activates below 40% load for silent operation, with the 92mm double ball bearing fan engaging smoothly as load increases. Professional-grade voltage regulation and ultra-low ripple ensure stable performance for demanding GPUs and CPUs during power fluctuations.
Next-Generation Ready with ATX 3.1 & PCIe 5.1 Support
Designed for the latest high-performance graphics cards, the SP850P features Lian Li’s proprietary 12V-2×6 connectors with soldered alloy terminals, delivering lower resistance and superior heat tolerance. The fully modular cable design with braided insulation offers maximum flexibility and clean cable management. Backed by a comprehensive 10-year hardware warranty and full protection suite (OCP, OVP, OTP, OPP, SCP, UVP).
