What reviewers say

The Hardware Busters review notes that the be quiet! Pure Power 13 M 850W is a fully modular, ATX v3.1 compliant PSU that delivers Platinum‑grade efficiency and very low noise (A++). The article highlights its silent operation, support for modern standards such as PCIe 5.1, and solid build quality from FSP.

The Honest Verdict gives the Be Quiet! Pure Power 13M 850W a solid editorial score of 8/10, praising its 80 Plus Gold efficiency, ATX 3.1 compliance, Japanese capacitors for longevity, and genuinely quiet operation backed by owner feedback. It notes that the unit is well‑built and reliable for most mid‑to‑high‑end gaming builds, but points out a few drawbacks: it lacks zero‑RPM mode (so it won’t stay completely silent), its semi‑modular cabling can be less convenient in tight cases, and its 5‑year warranty is shorter than some competitors’ longer warranties.
