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.
