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

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

The white SX Platinum from Lian-Li offers the same blend of high efficiency and strong stability at 850 watts, in a light finish suited to clean, white-themed builds. The unit carries an 80 PLUS Platinum certification and arrives with a fully modular design.

Power & efficiency

The supply provides 850 watts with a stable +12V and is intended for performance systems that demand dependable delivery. Pairing an 80 PLUS Platinum certification with the PPLP Platinum standard ensures a particularly high efficiency level and low energy losses. With full ATX 3.1 and PCIe 5.1 compatibility, the unit handles load spikes of up to 200% of rated output, for steady power even under peak loads.

Cables & connectors

Thanks to the fully modular design, you install only the cables actually required, which keeps the case organized and airflow unrestricted. Support for the ATX 3.1 and PCIe 5.1 standards lets you connect next-generation graphics cards directly and safely.

Reliability & cooling

The unit is built for long-term reliability with quality Japanese capacitors. A Smart Stop/Start function enables especially quiet operation: at 40% load or below the fan stops intelligently, and you can control this through a dedicated switch on the unit's rear. The supply carries a broad protection set covering OCP, OVP, OTP, OPP, SCP, UVP, NLP and SIP for full safety against overcurrent, overvoltage, heat and short circuits.
