On 13th November 2025, Lian Li unveiled its new SX line-up of high-power compact power supply units (PSUs). Featuring 80 PLUS Platinum certification and compliance with the ATX 3.1 standard, the SX line-up is available in black or white colourways, and comes equipped with a native 12V-2x6 power connector for next-generation graphics cards and multiple 8-pin PCIe power connectors for added flexibility in terms of the components that you can use in your PC build with this PSU. Equipped with a smart cooling system where the PSU's 120mm cooling fan only activates when the PSU is above 40% load, the key selling point for the SX lineup's got to be its compact size, where it measures in with a depth of just 140mm.
Available in 1200W (SX1200P), 1000W (SX1000P) and 850W (SX850P) variants, we'll be taking a closer look at the range-topping SX1200P variant for this video - watch on to learn more about the SX1200P and its features, and to see it as part of a demo build featuring Lian Li's new LANCOOL 217 INF PC case, HydroShift II LCD-S 360 TL AIO CPU cooler and a bunch of Uni Fan SL-Inf Wireless case fans!
