be quiet!, the German manufacturer for premium PC components, is proud to introduce Pure Power 13 M, the next evolution of its popular mainstream PSU line. Fully compliant with the ATX 3.1 standard, the Pure Power 13 M offers improved performance and high efficiency, modern PCIe 5.1 compatibility, a semi-passive cooling system that ensures virtually silent operation during low to medium loads and remarkably quiet active cooling under higher loads, and modular cables for a clean installation. This future-proof power supply is available in five wattages: 1000W, 850W, 750W, 650W, and 550W, each with 80 PLUS® Gold and Cybenetics Gold certification.

“With Pure Power 13 M, we’re delivering the features and performance users expect from be quiet!.” says Aaron Licht, CEO of be quiet!. “We’ve improved on our proven fan technology with a semi-passive mode as well as lower noise levels during active cooling. The result is a reliable and extremely quiet PSU that’s fully compatible with the latest GeForce RTX 5000 and Radeon RX 9000 series and that meets the needs of today’s and tomorrow’s PC builders.”

Gold-rated efficiency with semi-passive cooling
Thanks to a proven combination of LLC, SR, and DC/DC topology, Pure Power 13 M delivers exceptional stability and voltage regulation. Certified with both 80 PLUS® Gold and Cybenetics Gold, it achieves high efficiency levels while maintaining low power consumption. A newly introduced semi-passive cooling mode allows the 120mm be quiet! fan to remain off under low and moderate loads, ensuring a virtually inaudible operation when full cooling isn’t necessary. When active, its airflow-optimized blades and temperature-controlled curve maintain the company’s hallmark quiet performance.

Designed for next-gen hardware
Pure Power 13 M fully supports Intel’s ATX 3.1 specification and is PCIe 5.1 ready, featuring a 12V-2x6 connector delivering up to 600W1 for the most demanding graphics cards, alongside up to four traditional PCIe 6+2 connectors2. The stricter safety standards of ATX 3.1 ensure improved support for next-gen GPUs. This makes it a highly compatible solution for both current high-end setups and future upgrades.

Improved design and functionality
Pure Power 13 M features a single 12V rail for stronger, more consistent power delivery and includes fully modular cable management, making cable routing easier and reducing clutter inside the chassis. The PSU is housed in a sturdy steel enclosure and continues to reflect be quiet!’s high standards in design and manufacturing, with quality assurance conducted in Germany. All models are backed by a 10-year manufacturer’s warranty, reinforcing be quiet!’s commitment to reliability and customer satisfaction.
