The Lian Li SX1200P is a recent power supply offering. This fully modular, Platinum-rated unit is compatible with ATX 3.1 and PCIe 5.1 standards and comes with a 10-year warranty. It features high-grade Japanese capacitors and is suitable for various smaller PC cases due to its compact 140mm depth. This review examines whether the SX1200P justifies its $160 price point.

Lian Li provides this power supply series in three wattage options: 850W, 1000W, and the 1200W model under review. Both white and black color schemes are available. While Lian Li states 80 Plus Platinum certification, Cybenetics certifications were not provided for this unit, nor were they present on the packaging or in the documentation. Lian Li indicated that Cybenetics certification is in progress, but no details were available at the time of publication.
