Description
The LIAN LI SP850 V2 Gold is a premium SFX power supply engineered for enthusiasts who refuse to compromise on performance within compact chassis. Measuring just 125mm x 100mm x 63.5mm, this unit delivers up to 850W of 80 PLUS Gold certified power with over 90% efficiency at typical loads. With the inclusion of ATX 3.1 standards and a native 12V-2x6 cable, it ensures seamless compatibility with the latest NVIDIA GeForce RTX 40-series and future-gen graphics cards, providing a clean, efficient, and future-proof power solution for high-end SFF builds.
This product is for:
- SFF Enthusiasts: Builders using Mini-ITX cases like the LIAN LI Q58 or A4-H2O who need maximum power in a minimal footprint.
- High-End Gamers: Users running RTX 4080 or 4090 GPUs who require the stable power delivery and transient response of the ATX 3.1 standard.
- Aesthetic-Focused Builders: Those seeking a clean look with the choice of black or white finishes and flexible, embossed modular cables.
- Silent PC Advocates: Users who value the Zero RPM mode, which keeps the 92mm FDB fan stationary during low-load tasks for absolute silence.
- Long-Term System Planners: Builders looking for a reliable core component backed by a comprehensive 10-year warranty and full protection circuits.

Installing the SP850 V2 is a streamlined experience thanks to its fully modular design and unique embossed cables. These cables are softer and more pliable than standard sleeved versions, making cable management in tight quarters significantly easier. The native 12V-2x6 cable is a standout feature, eliminating the cable clutter often seen with 12VHPWR adapters against case side panels. During operation, the unit remains virtually silent under light loads, and even under heavy gaming sessions, the 92mm fan maintains a controlled acoustic profile without the high-pitched whine common in smaller PSUs.
Compared to the previous V1 model, the SP850 V2 introduces critical updates for modern hardware, most notably the transition to ATX 3.1 and the inclusion of the improved 12V-2x6 connector. While standard ATX power supplies offer similar wattages, the SFX form factor of the SP850 V2 allows for significantly more airflow and component clearance in compact cases. It competes directly with premium SFX units like the Corsair SF series, distinguishing itself with its specific 12V-2x6 cable design and LIAN LI's signature aesthetic matching for their popular chassis line.
Q&A:
- Does the LIAN LI SP850 V2 support the NVIDIA RTX 4090? Yes, it includes a native 12V-2x6 cable designed to handle the high power excursions of the RTX 40-series GPUs.
- What is the benefit of ATX 3.1 over ATX 3.0? ATX 3.1 improves upon the 12VHPWR connector with the 12V-2x6 standard, offering better physical engagement and improved safety margins.
- Will this fit in a standard ATX case? Yes, though it is an SFX unit, it can be mounted in ATX cases using an SFX-to-ATX adapter bracket, which is often sold separately.
- How does the Zero RPM mode work? The 92mm fan will not spin until the power load or temperature exceeds a certain threshold, ensuring silent operation during web browsing or office work.
- What is the difference between the SP750 V2 and SP850 V2? The primary difference is the total power output (750W vs 850W), allowing the SP850 V2 to support higher-tier CPUs and GPUs with more headroom.
