Lian Li Unveils SP Platinum Series SFX Power Supplies for High-End SFF Builds

Lian Li, renowned for its premium computer chassis and accessories, has introduced the SP Platinum Series—fully modular SFX power supplies available in 850W and 1000W variants. Designed specifically for high-performance small-form-factor (SFF) systems, these power supplies deliver 80 Plus Platinum certified efficiency and meet the latest Intel ATX 3.1 and PCIe 5.1 standards. With advanced engineering and robust features, the SP Platinum Series is tailored for enthusiasts seeking reliable, efficient, and quiet power delivery in compact PC builds.

80 Plus Platinum Efficiency and Next-Generation Compliance

The SP Platinum Series achieves up to 92% efficiency at 50% load, earning the prestigious 80 Plus Platinum certification. This high efficiency ensures reduced energy waste and lower operating temperatures, which is essential for maintaining system stability in compact enclosures. The power supplies are fully compliant with Intel ATX 3.1 and PCIe 5.1 specifications, supporting the latest hardware requirements for modern CPUs and GPUs.

To ensure reliable GPU power delivery, Lian Li has integrated its proprietary 12V-2x6 cable, engineered with alloy copper terminals for improved conductivity and thermal performance. The dual-color connector design provides a clear visual confirmation of proper insertion, enhancing both safety and ease of installation.

Premium Components and Comprehensive Protection

Each SP Platinum unit is built with 100% Japanese 105°C capacitors, known for their durability and stable power output. The power supplies are equipped with a full suite of protections, including Over Current Protection (OCP), Over Voltage Protection (OVP), Over Temperature Protection (OTP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), No Load Protection (NLP), and Surge & Inrush Protection (SIP). This comprehensive protection ensures long-term reliability and safeguards connected components against electrical faults.

Silent Operation and Service-Friendly Features

For quiet computing, the SP Platinum Series features a 92mm fluid dynamic bearing (FDB) fan with a smart thermal curve. The fan remains completely off at loads of 40% or less, eliminating noise during idle or low-power operation. This makes the SP Platinum ideal for users who prioritize silent performance in their SFF builds.

Addressing the challenges of internal PSU mounting, each unit includes an IEC 320 C14-to-C13 extension cord with an inline on/off switch. This allows users to control power externally, even when rear AC access is restricted, streamlining maintenance and system management.

Optimized Cable Management and Versatile Compatibility

The SP Platinum Series comes with super-flexible, braided modular DC cables, designed for easy routing in tight spaces. These cables simplify cable management, reduce clutter, and promote better airflow within small-form-factor cases. For added versatility, an SFX-to-ATX bracket is included, enabling seamless installation in both SFF and standard ATX enclosures.

Color Options and Availability

The Lian Li SP Platinum Series SFX power supplies will be available in both black and white finishes, catering to a variety of build aesthetics. The series is set to launch on November 14th, 2025, offering PC enthusiasts a new standard in efficient, reliable, and quiet power delivery for compact systems.
