| 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 (X 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 has all required components plus one extra X capacitor and two extra Y capacitors. The MOV is behind the fuse on Figure 8 and thus not shown.  click to enlarge Figure 7: Transient filtering stage (part 1).

Now let’s have a more detailed discussion on the components used on Corsair HX850W. |
