be quiet! Pure Power 13 M 1200W Review (2026)

We wouldn't expect anything else from be quiet!, it's a simple dark box with orange accenting. The front highlights the two Gold certification badges from both Cybenetics and 80 Plus. We did confirm with be quiet! about the gold badge as we know these units actually achieved Platinum certification with Cybenetics, and they said ‘the test sample [with Cybenetics] might [have] been an outlier and we want to represent the efficiency level honestly'. So there you go.

The rear of the box has some information along the top with the same Gold certification badges and an overview of the power output, along with a PCIe 5.1 badge.

be quiet! include a little user manual, cable ties, mounting screws and a power cable.

Cable quality seems really good, between 16-18 AWG gauge cables. The main 600W 12+4 pin PCIe cable is 16-24AWG.

The cable lengths all seem fine to me even for larger cases, and there are plenty to support a reasonably high end system with a 50 series GPU.
