Was to make the living room suitable for looking for a quiet power supply to my PC. The Be quiet! Pure Power CM BQT L8-CM-630W turned out to be a very good choice. The power supply unit is in operation so softly that it almost nothing heard even if you hold the head right next to it. The included cables are long enough for larger PC case and the flexible cable Managemend just class. Finally no more senseless clutter in the housing.
Conclusion: strong buy recommendation for each of a low, powerful PSU investigated.
