The be quiet! Pure Power 12 is an 850W power supply unit designed for PC builds requiring stable and efficient power. It complies with the ATX 3.1 standard and includes native PCIe 5.1 support, providing a 12VHPWR connector for current-generation graphics cards. The unit operates on a single 12V rail design to ensure consistent power delivery to all components under load. Its 80 PLUS Gold certification signifies a high level of energy efficiency, reducing wasted heat and operational costs. This PSU is built to handle the demands of modern gaming and workstation systems.
This model is housed in a standard ATX chassis measuring 160 mm in depth, facilitating installation in most mid-tower and full-tower cases. Cooling is managed by a single 120 mm fan engineered for quiet operation, maintaining low noise levels even as power draw increases. The PSU includes a comprehensive suite of protection circuits, such as over-voltage, over-power, and short-circuit protection, to safeguard system components. The unit is equipped with a combination of sleeved and flat cables to assist with cable management and airflow within the chassis.
