Power Supply LIAN-LI SX black SX1000P-B 80 Plus Platinum 1000W

Lian-Li SX 1000W Platinum Black Power Supply

Lian-Li's SX Platinum line is aimed at builders after uncompromising stability and top-tier efficiency. This 1000W unit in a black finish carries 80 PLUS Platinum and PPLP Platinum certification, with full compatibility for the ATX 3.1 and PCIe 5.1 standards. It supplies a stable +12V rail alongside high durability thanks to quality Japanese capacitors.

Power & efficiency

A continuous 1000W output offers broad reserve for high-performance systems and supports load spikes up to 200% of the nominal rating to keep delivery steady during peaks. The 80 PLUS Platinum and PPLP Platinum certifications ensure high efficiency, seen in lower power draw and less wasted heat. That steady power helps deliver a smooth, reliable gaming experience even under heavy load.

Cables & connectors

The unit supports the ATX 3.1 and PCIe 5.1 standards and is meant to feed next-generation graphics cards in line with their power needs. A fully modular design lets you install only the cables required, keeping the system tidy, efficient and ready to show off. This trims unnecessary cable clutter and improves airflow inside the case.

Reliability & cooling

The unit offers quiet, fanless cooling up to 40% load, leaving it completely silent at low demand. A Smart Stop/Start function puts the fan into an intelligent stop mode when load drops below 40%, and it can be switched on or off via a dedicated control on the back of the supply. A comprehensive protection system covering OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP guards against overcurrent, overvoltage, overheating, overload and short circuit. Long-term durability rests on quality Japanese capacitors.
