A Look Inside The Fusion 550RF
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 Figure 4, you can see how the manufacturer added a “tunnel” in front of the fan in order to increase the airflow on the area between the switching transistors heatsink and the secondary heatsink. Not a bad idea at all.
