Modularity and performance at its best: Lian Li SX Platinum

The SX Platinum series comes in three power variants (850W, 1000W, 1200W) and in both black and white, so it fits not only powerful but also visually coordinated builds. Its 80 PLUS Platinum rating delivers high efficiency—up to around 94% conversion efficiency in favorable load ranges—resulting in less heat, quieter operation, and better long-term energy use. The unit is fully modular, uses premium 105°C Japanese capacitors, and—with ATX 3.1 compatibility—offers load handling tuned for today’s flagship hardware.

A major focus of the SX Platinum is modern GPU-ready connectivity: PCIe 5.1 12V-2×6 support helps provide stable and safe power delivery to the newest graphics cards. A practical visual extra is the braided-texture cabling with included cable combs, which helps achieve tidy cable management and improves the overall look—especially in tempered-glass cases. Thanks to the fully modular design, only the cables you actually need go into the build, which can noticeably improve airflow and simplify installation.

With the SX Platinum, Lian Li includes a full protection suite: OPP, OVP, SCP, OCP, OTP, SIP, and UVP—designed to keep the system predictable and safe under load. A 10-year warranty is a strong commitment that provides long-term peace of mind even in the premium segment. With a 100,000-hour MTBF rating, 105°C Japanese capacitors, and active PFC, the platform provides a solid foundation for high-draw gaming PCs, creator systems, and workstation builds.

The SX Platinum shines where ‘good enough’ no longer works for ATX systems: a high-power GPU, a strong CPU, many peripherals, and sustained load demand a stable, efficient, and well-cooled PSU. Its modern 12V-2×6 connector and ATX 3.1 foundation make it a notably future-proof choice, while the braided cables are not just aesthetic—they also speed up the build process. For high-end builders who want to be confident about the PSU, the SX Platinum is hard to ignore.

The Lian Li SX Platinum is aimed at builders putting together a strong, modern ATX configuration who don’t want to compromise on efficiency, protection, or component quality. It’s an excellent match for top-tier gaming PCs, creator machines, and workstations where stability and quieter operation are real, tangible advantages. If long-term planning and GPU-optimized connectivity matter, the SX Platinum is a very strong premium option.
