be quiet! System Power 9 400W CM - PSU, 80 Plus Bronze

The be quiet! System Power 9 400W CM is a power supply unit designed for mainstream and budget-conscious PC builds. It provides a continuous power output of 400 watts with an 80 PLUS Bronze certification, indicating an efficiency of up to 89% under typical loads. This level of efficiency helps to reduce heat generation and energy consumption. The semi-modular cabling system allows for the attachment of only necessary cables, which can improve internal airflow and simplify the build process by reducing clutter within the case.

This unit is equipped with a temperature-controlled 120mm fan that adjusts its speed based on system load to maintain a balance between cooling performance and low-noise operation. It incorporates active Power Factor Correction (PFC) and a comprehensive suite of protection circuits, including over voltage, over power, and short circuit protection, to safeguard system components. The ATX form factor ensures compatibility with a wide range of standard computer chassis, and the unit includes two 6+2 pin PCIe connectors to support a dedicated graphics card.
