| Transient Filtering Stage |
 As we mentioned on other articles and reviews, the first place we like to take a look when opening a power supply to have a hint about its quality is its filtering stage. The recommend components for this stage are two ferrite coils, two ceramic capacitors (Y capacitors, usually blue), one metalized polyester capacitor and one MOV (Metal-Oxide Varistor). Very low-end power supplies use fewer components than that, usually removing the MOV and the first coil. This power supply is flawless on this stage, having one more ferrite coil, two more Y capacitors (two of them are soldered directly to the main AC connector) and two more X capacitors than necessary.
