The be quiet! Pure Power 12 M 1000W is a fully modular power supply designed to provide stable energy for high-performance computers. It adheres to the ATX 3.0 and ATX 12V 3.1 standards, featuring a continuous power output of 1000 W and an 80 PLUS Gold efficiency rating that reaches up to 93.1%, which helps reduce energy waste and heat during operation. To support modern graphics cards, it includes a dedicated 12V-2x6 connector capable of delivering up to 600 W, alongside four 6+2-pin PCIe connectors and multiple SATA and Molex ports. Its internal design utilizes an LLC + SR + DC/DC topology to ensure clean power delivery across two independent 12V rails. A 120 mm silence-optimized fan with a rifle bearing keeps the unit cool while remaining remarkably quiet, with noise levels as low as 9.3 dBA under light loads. The black chassis measures 160 x 150 x 86 mm and weighs 1.91 kg, fitting comfortably into most standard cases. Because the cabling is fully modular, you only use the wires your build actually requires, which simplifies cable management and improves airflow. The set includes sleeved cables for the motherboard and 12V-2x6 connection, while the rest are flat for a cleaner look. This unit is well-suited for enthusiasts building powerful workstations or gaming rigs who need a reliable, quiet power source with comprehensive protections like OTP, OCP, and SCP to keep their components safe.
