We decided to disassemble this power supply to see how it looks like inside, what is the design used and what components are used. Please read our Anatomy of Switching Power Supplies tutorial to understand how a power supply works inside and to compare this power supply to others.

In this page we will have an overall look, while on the next page we will discuss in details the quality and rating of the components used.

We can point out several differences between this power supply and a very low-end (a.k.a. “generic”) one: the construction quality of the printed circuit board (PCB); the use of more components on the transient filtering stage; the power rating of all components; the design; etcetera.

On Figures 7 and 8 you can have an overall look from inside this power supply.
