Have in my computers now only power supplies Be Quiet installed. Even the entry-level model as here the PurePower afford a great job. Great processing and no problems. My Crossfire team together with an overclocked Phenom II X6 are for the 630W power supply is no problem (-> noisy outlet flow meter is the maximum consumption of the computer without a screen etc. under high load at about 570 watts.). Compared with the Pure Power L7 which I, the voltage values have also possess not improved but the CM L8 you get for the same price a in my opinion a slightly quieter fan, sleeved cables and cable management.
