The Pure Power 13 M has a very simple enclosure design – a “be quiet!” branding is embossed on the side. If your PC chassis has a bottom-mounted PSU bay and without a shroud, this would be the visible side of the PSU.


The top of the PSU is completely free of labels or markings, which is something I personally prefer. On many power supplies, this area is often covered with an information sticker detailing specifications and certifications.


The opposite side of the PSU houses the information label, which includes essential details such as the model name, certifications, electrical specifications, and the unit’s serial number.


At the rear, the layout is kept simple, featuring only the power cord socket and the main power switch. Although the PSU supports semi-passive cooling, there is no dedicated toggle to enable or disable this function manually.


All PSU connectors are clearly labelled for easy identification during installation.


The Pure Power 13 M series also shares cable compatibility with several older be quiet! power supplies, which can be verified through the brand’s cable compatibility checker on the be quiet! website. This allows users upgrading from an older be quiet! PSU to reuse their existing cables or keep them as spares.
