LIAN LI Launches 850W SFX PSU with 12VHPWR Cable - SP850


LIAN LI Industrial Co. Ltd., a leading manufacturer of aluminum chassis and PC accessories, announces the SP850, a fully modular SFX PSU with included 12VHPWR power cable. Sharing the same aluminum housing as the previously launched SP750, the 80 PLUS Gold certified SP850 is perfect for future-proofing small form factor builds for power-hungry components. Built with high-quality premium 100% Japanese capacitors, the SP850 offers quite reliable performance with zero RPM mode under 40% load.

Next-gen Ready Power Connector

With an included, 400mm, 16 AWG thick 12VHPWR PCIe 5.0 compatible connector capable of delivering up to 400W, the SP850 provides adequate power for the latest GPUs and prepares users for any next-gen upgrades.

Improved Efficiency and Safety

The SP850 now features a 92mm hydraulic bearing fan that stays at zero RPM until the unit reaches 40% load or 60°C ambient temperature. Even as the fan gradually increases speed, it maintains a maximum noise level of 40.6 dBA at 2800 RPM. LIAN LI has now improved their SFX PSU lineup even more, as the SP850 delivers 91.55% power efficiency at 50% load, which exceeds the 80 PLUS GOLD standard of 90% efficiency at the same load. Protection features have also been improved, with the SP850 now featuring an additional inrush current limiter.

Sleek Clean Look Like many of LIAN LI’s case exteriors, the SP850 is built in sleek aluminum and steel housing. The black version includes a brushed aluminum finish whilst the white version is

powder coated with silver accents. Both colors come with matching braided cables, providing modularity and flexibility for a clean build.
