A key feature of the Pure Power 13 M is its 120 mm be quiet! cooling fan (model BQ QF2-12025 HS), rated for speeds of up to 2000 RPM. While this specific model does not directly correspond to any retail be quiet! case fan, its blade design closely resembles that of the Pure Wings 3 series, albeit housed in a more conventional fan frame. Even so, it retains the brand’s iconic Pure Wings fan blade design, reinforcing its focus on efficient airflow and low-noise operation.


The Pure Power 13 M PSU's OEM manufacturer is FSP. The Pure Power 13 M 1000W is equipped with two primary capacitors and heatsinks to assist heat dissipation.


The PSU is equipped with two 470uF 420V 105°C PL(M) Series aluminium electrolytic capacitor manufactured by Elite (Taiwan Chinsan Electronic Group). The PSU’s secondary capacitors are also sourced from the same company.


Be quiet! appears to be using the same PCB for all the models under the Pure Power 13 M Series and it is encouraging to know that the 1000W model surpasses the Cybenetics Gold efficiency rating, achieving Cybenetics Platinum rating overall. See Cybenetics certification here.
