The LIAN LI SX0850P is an 850W power supply unit designed for systems requiring stable, efficient power delivery. It complies with ATX 3.1 and PCIe 5.1 standards, ensuring support for current-generation and future hardware components. The unit delivers 850 watts of continuous power and features an 80 PLUS Platinum certification, which signifies high efficiency and lower heat generation under load. Its standard ATX form factor is housed within a compact 140mm deep chassis, making it suitable for a variety of PC cases, including those with limited internal space.
This model utilizes a fully modular cabling system, which allows for the use of only necessary cables to improve case airflow and simplify cable management. Cooling is handled by a 120mm fan operating in a hybrid mode; it remains inactive at loads below 40% for silent operation during low-demand tasks. The power supply is finished in white and includes sleeved cables for builders focusing on a specific aesthetic. A comprehensive set of electrical protections, including Over Current Protection (OCP) and Over Voltage Protection (OVP), is integrated to safeguard internal components.
