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.

On Figures 3 and 4 you can have an overall look from inside GlacialPower GP-PS550BP. The transformer on the upper right corner in Figure 3 and on the left side in Figure 4 is the passive PFC transformer. As you can imagine, passive PFC solutions add more weight to the power supply.
