Overview

The be quiet! Pure Power 13 M 850W is an ATX 3.1 compliant, fully modular 850W power supply built for quiet, reliable modern PC builds. It ships with a native 12V-2x6 connector delivering up to 600W to PCIe 5.1 graphics cards plus 4 PCIe 6+2 connectors for current-gen GPUs, making it versatile across present and future systems. A semi-passive 120mm rifle-bearing fan stays off at low loads, and the LLC + Synchronous Rectifier + DC to DC topology with a single high-performance +12V rail absorbs transient loads up to double rated power. Backed by a 10-year warranty, the Pure Power 13 M 850W is an excellent choice for quiet gaming and performance PC builds.
