Be Quiet! Pure Power L8 700W PSU Review

Testing results (Regulation & Ripple)

Considering the league of the Pure Power L8 700 W power supply, the electrical performance of the unit is excellent. Ripple suppression is very good, especially while the load of the power supply is low to medium. Under heavy load, the voltage ripple nearly doubles, reaching up to 56 mV on the 12 V line; however, even then, these ripple figures are less than half of the 120 mV design limit. Voltage regulation is very good as well, at about 2% on the 5 V and 12 V lines and at 2.8% on the 3.3 V line.
