Logisys PS350MA Power Supply Review
Transient Filtering Stage
Contents
As we have mentioned in other articles and reviews, the first place we look when opening a power supply for a hint about its quality, is its filtering stage. The recommended components for this stage are two ferrite coils, two ceramic capacitors (Y capacitors, usually blue), one metalized polyester capacitor (X capacitor), and one MOV (Metal-Oxide Varistor). Very low-end power supplies use fewer components, usually removing the MOV and the first coil.
This power supply doesn’t have this stage! The place for installing the components are there, but the manufacturer, in order to cut costs, decided not to install them.
