A Look Inside The Zalman ZM770-XT

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.

This page will be an overview, and then in the following pages we will discuss in detail the quality and ratings of the components used. The first thing we notice was how the connectors from the modular cabling system are installed to the main printed circuit board. Instead of using a bunch of wires like it usually happens on power supplies with this kind of system, it is soldered to it through some pins. This is a terrific solution, as it reduces the number of wires inside the unit and thus improves airflow.
