Description
The Lian Li SP850 and SP1000 Platinum power supplies redefine power density for small-form-factor builds. By integrating the latest ATX 3.1 standards and a native 12V-2x6 600W cable into a compact 100mm deep SFX chassis, Lian Li ensures that even the most space-constrained systems can house high-end NVIDIA 40-series and future GPUs. With 80 PLUS Platinum certification, these units achieve up to 92% efficiency at 50% load, significantly reducing heat waste and electricity costs while maintaining a premium aesthetic in both black and white finishes.
This product is for:
- SFF Enthusiasts: Optimized for Mini-ITX cases like the Lian Li A4-H2O where internal space is at a premium.
- High-End Gamers: Provides the 1000W overhead and dedicated 12V-2x6 connector required for RTX 4090 and high-TDP processors.
- Professional Workstation Builders: Features 100% Japanese Rubycon 105°C capacitors to ensure 24/7 stability for rendering and AI tasks.
- Aesthetic-Focused Builders: Includes premium braided cables that are easier to route and look better than standard plastic-sleeved alternatives.
- Long-Term System Owners: Backed by a 10-year warranty and ATX 3.1 compliance, offering peace of mind for multiple hardware upgrade cycles.

Installing the Lian Li SP series is remarkably straightforward thanks to its fully modular design and flexible braided cables. Unlike the stiff plastic cables found in many budget units, these braided wires route easily through tight corners and narrow cable management channels in compact cases. During operation, the 92mm FDB fan remains completely silent under low-to-medium loads, only spinning up when necessary to maintain optimal temperatures. The build quality is evident in the SECC steel housing, providing a premium tactile feel that matches its high-performance internal components.
Compared to standard ATX power supplies, the SP850/SP1000 offers a significantly smaller footprint without sacrificing wattage, making it the superior choice for modern compact builds. While many SFX units on the market stop at 80 PLUS Gold, the SP series moves to Platinum, offering better thermal management and a lower noise floor. Against older SFX models, the inclusion of the ATX 3.1 12V-2x6 cable eliminates the need for bulky 8-pin adapters, streamlining the internal airflow and improving the safety of high-power GPU connections.
Q&A:
- Does the Lian Li SP1000 support the RTX 4090? Yes, it includes a native 12V-2x6 cable capable of delivering up to 600W, meeting the power requirements for high-end GPUs.
- Can I use this SFX PSU in a standard ATX case? Yes, a dedicated SFX-to-ATX mounting bracket is included in the box for maximum case compatibility.
- Is the fan always running? No, the unit features a smart Zero RPM mode that keeps the fan off during low-load scenarios for silent operation.
- What is the benefit of ATX 3.1 over ATX 3.0? ATX 3.1 introduces the improved 12V-2x6 connector, which offers better physical contact and safety compared to the original 12VHPWR design.
- Are the internal components high quality? The unit utilizes 100% Japanese Rubycon 105°C capacitors, which are industry-leading for longevity and heat resistance.
