be quiet! Pure Power 13 M 550W ATX v3.1 PSU Review

Box & Bundle

Typically, the box features a photo of the product on its front. On the same side, you will find the efficiency badges and the model number, along with a description of the capacity. Around the back are more details on the product’s technical specifications.

Product Photos

Although the exterior design doesn’t feature any exotic elements, the elegant fan grille, ruffled fan wings, and white accent around the fan form an appealing combination. On the unit’s front side, there is no switch to enable or disable semi-passive operation. On the same side, you will find the AC receptacle and the power switch.

The modular panel features eight sockets, including a native 12V-2×6 header with a maximum power output of 300W.

The number of available cables and connectors is sufficient to handle the PSU’s max power. The same applies to cable length, as a 550W PSU is unlikely to be installed in a chassis of cave-like size. Moreover, the shorter the cables, the lower the energy losses, which is why some brands tend to send PSUs with ultra-short cables for efficiency certification in schemes that do not specify cable length in their reports. Lastly, the distance between the peripheral cables is ideal, at 150mm.

  1. Are you willing to evaluate the lowest category Be Quiet series as well? Most notably the brand new System Power 11 series? It has 450W and 550W members, and it is the cheapest Be Quiet PSU on the market. A lot of people are buying them, without knowing how dangerous (or safe?) they are, after the System Power 10 test turned out that they are not that terrible, contrary to the tribal knowledge (System Power 10 Bronze series has been downgraded to Tier E on the SPL PSU Tier list).
