Power Supply LIAN-LI SX black SX0850P-B 80 Plus Platinum 850W

Lian-Li SX 850W Platinum Black ATX 3.1 Power Supply

Lian-Li's SX Platinum line targets builders after uncompromising stability at 850 watts, with an 80 PLUS Platinum certification and support for the latest standards. Its black finish and fully modular design make it a solid foundation for a tidy, powerful system.

Power & efficiency

The unit delivers a stable +12V at 850 watts and suits performance-heavy systems. An 80 PLUS Platinum certification alongside the PPLP Platinum standard ensures high efficiency and low losses. Full compliance with ATX 3.1 and PCIe 5.1 lets it withstand load spikes of up to 200% of nominal output, for steady power even under demanding conditions.

Cables & connectors

The fully modular design lets you install only the cables you need, keeping the system orderly, efficient and ready for display. Support for the ATX 3.1 and PCIe 5.1 standards provides a direct and reliable connection to next-generation graphics cards.

Reliability & cooling

High reliability comes from quality Japanese capacitors. A Smart Stop/Start mechanism keeps things fully silent at low loads: when the load drops to 40% or below, the fan enters an intelligent stop mode, and the function can be turned on or off via a dedicated switch on the rear of the unit. A comprehensive protection system covers OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP against overcurrent, overvoltage, overheating, overload and short circuits.
