be quiet! Pure Power 11 FM (650W) Power Supply Review

Ripple

Although be quiet! doesn’t make much of a song or dance about the ripple performance of the Pure Power 11 FM, we’re not entirely sure why not. As can be seen in our results below, this PSU was exceptionally good at providing the juice in an exceptionally clean manner. With the vast majority of the results in single-digit (whole) territory, these are exceptionally impressive and certainly more than a little indicative of a quality design.
