The be quiet! Pure Power 12 M is an ATX power supply unit that provides a nominal output of 1000W. It meets the 80 PLUS Gold standard, operating with an efficiency of up to 93.2% under typical loads. Compliant with the ATX 3.1 specification, this PSU is designed to handle the high power excursions of current-generation hardware. The inclusion of a native 16-pin PCIe 5.0 connector provides direct compatibility with modern graphics cards without requiring adapters.
This unit features a fully modular cabling system, enabling users to connect only the required cables for improved airflow and a cleaner internal layout. Cooling is managed by a temperature-controlled 120mm rifle bearing fan, which operates at low speeds or stops entirely under light loads to reduce noise. For system protection, it incorporates a suite of safety features, including protections against over current, over power, over voltage, overheating, and short circuits. The internal components are rated for an operational life with a mean time between failures of 100,000 hours.
