A Look Inside The Green Star 450 W
We decided to disassemble this power supply to see what it looks like inside, how it is designed, and what components are used. Please read our Anatomy of Switching Power Supplies tutorial to understand how a power supply works and to compare this power supply to others.
In this page, we will have an overall look, while in the next page we will discuss in details the quality and rating of the components used.
The first impression we had when opening this power supply was that we were in front of a very low-end (“generic”) unit that was put inside a nice housing as the printed circuit board was too small for the size of the housing, as you can see in Figure 4. Let’s see if this was just an impression or if there is some truth about our hunch.
