The MONTECH CENTURY II 850W is an ATX power supply engineered for high-performance computer systems. It provides a total power output of 850 watts and meets the 80 PLUS Platinum certification, indicating high energy efficiency across various operational loads. Adherence to the ATX 3.1 specification ensures compatibility with modern hardware, including support for transient power excursions from high-end graphics cards. The unit incorporates active Power Factor Correction (PFC) to maintain a stable and reliable electrical output.
This PSU features a fully modular cabling system, which enables builders to connect only the required cables for a cleaner build and improved internal airflow. A 135mm fan manages thermal performance and is designed for low-noise operation, with a silent mode that activates under light system loads. The chassis is a standard ATX form factor, measuring 150 x 140 x 86 mm, with a metallic silver finish. A comprehensive set of protection features, such as Over Voltage Protection (OVP) and Over Current Protection (OCP), is included to safeguard connected components.
