Lian Li launches new SX PSUs with ATX 3.1 and Platinum efficiency

Lian Li has expanded its power supply portfolio with the launch of the SX series. Available in 850W, 1000W, and 1200W capacities, these new units are designed to meet the Intel ATX 3.1 specification and carry 80 Plus and PPLP Platinum certifications, promising up to 92% efficiency under typical loads.

Ready for the latest graphics cards, each SX series unit includes a native PCIe Gen 5.1 12V-2×6 connector capable of delivering up to 600W without the need for bulky adapters. For the higher wattage 1000W and 1200W models, Lian Li also includes a 12V-2×6 to dual 6+2 PCIe cable to ensure compatibility with a wider range of peripherals and older cards. The units ship with flexible, braided-texture modular cables designed to facilitate easy routing in tight chassis.

Internals are cooled by a 120 mm fluid dynamic bearing fan. This cooling solution features a Zero RPM mode, which stops the fan completely under light loads for silent operation. A physical switch on the rear of the PSU allows users to toggle this hybrid mode on or off depending on their noise preference. Under the hood, the SX series is constructed using 100% Japanese 105°C capacitors and uses a single +12V rail layout.

Aesthetically, the casing features an embossed mesh pattern to assist with ventilation. As expected for a high-end unit, it comes with a comprehensive suite of industrial-grade protections, including OPP, OVP, SCP, OCP, OTP, UVP, SIP, and NLP, to safeguard the hardware. The Lian Li SX series is now available for pre-order in black and white, and it comes with a 10-year warranty. The SX850P costs £109.99/$119.99/€124.90, the SX1000P costs £130.99/$149.99/€149.90, and the SX1200P costs £139.99/$159.99/€159.90 for the flagship.
