LIAN LI Launches SP Platinum SFX Series PSUs with 80 PLUS® Platinum Certification
November 14th, 2025, Taipei, Taiwan – LIAN LI, a leading manufacturer of computer chassis and accessories, announces the SP Platinum Series, fully modular 850W and 1000W SFX power supplies engineered for high-end small-form-factor builds. Delivering 80 PLUS® Platinum certified efficiency, the SP Platinum meets Intel ATX 3.1 and PCIe 5.1 requirements and integrates LIAN LI’s in-house designed 12V-2x6 for reliable modern GPU power delivery. It features a 92mm FDB fan with a smart curve that is powered off at ≤40% load for silent operation. For tighter cable management and easier routing, it includes super-flexible braided modular DC cables, along with an extension power cord featuring an inline on/off switch, which enables external power control. Built with 100% Japanese 105°C capacitors and a full protection suite, each unit ships with an SFX-to-ATX bracket for broader chassis compatibility.
Platinum Power, Next-Gen Standards
The SP Platinum Series is 80 PLUS® Platinum certified, delivering up to 92% efficiency at 50% load, while maintaining precise regulation and low ripple under changing workloads. The PSU series fully complies with Intel ATX 3.1 and PCIe 5.1 standards and comes with an in-house engineered 12V-2x6 GPU cable, built with alloy copper terminals for lower contact resistance, higher thermal tolerance, and a dual-color connector to facilitate a clear insertion check. For longevity and clean output, the SP Platinum utilizes 100% Japanese 105°C capacitors, and it’s protected by a comprehensive suite of protections, including OCP, OVP, OTP, OPP, SCP, UVP, NLP, and SIP, which cover overcurrent, over/under-voltage, over-temperature, short-circuit, and more.
Service-Friendly Power Control and Quiet Operation
For builds where the PSU is mounted internally and rear AC access is limited, each unit includes an IEC 320 C14-to-C13 extension cord with an inline on/off switch, allowing users to turn off their PSU without needing to open their case. The SP Platinum is also equipped with a 92mm FDB fan, which features a smart thermal curve that enables the fan to completely stop at loads of 40% or less, effectively eliminating idle noise.
Clean Routing for SFF, Drop-In ATX Compatibility
The SP Platinum comes with super-flexible, braided-texture modular DC cables, making cable management in tight, small-form-factor cases easier. These cables bend easily around components, reducing clutter for better airflow. An SFX-to-ATX bracket is included, allowing the SP Platinum to mount seamlessly in standard ATX enclosures.
Availability
The LIAN LI SP Platinum Series PSUs are available in black or white starting November 14th, 2025.
