The be quiet! Pure Power 13 M 650W is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The Pure Power 13 M series by be quiet! is a line of fully modular ATX power supplies aimed at users who want a balance of performance, efficiency, and silent operation. All models are certified by Cybenetics, achieving Platinum efficiency and a perfect noise score (LAMBDA A++). One of the standout features is full support for the ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with the latest GPUs and next-gen components, including high-powered cards like the NVIDIA RTX 40/50 series. It is not common to see a 550W ATX v3.1 compliant power supply, but the Pure Power 13 M line does.

From a design standpoint, the Pure Power 13 M units emphasize quiet operation, employing a custom 120mm fan from be quiet! known for its low noise levels even under load. The modular cabling system is a practical addition, helping reduce clutter and improve airflow within the case. With models ranging from 550W to 1000W, the series offers flexibility for different system builds, from mid-range desktops to high-performance gaming rigs. This is not a high-end line, targeting users who want a good-performing and quiet PSU without breaking the bank.
In today’s review, I will evaluate the 650W member of the line, which has enough capacity to support a mid-level gaming system. Don’t forget that ATX v3.1 PSUs can handle transient loads as high as double their capacities!
