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 inside 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.

We can point out several differences between this power supply and a 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 active PFC circuitry; the power rating of all components; the design; etcetera.

The first thing that caught our eye was the use of two main transformers instead of just one. So far we’ve seen only another power supply using two transformers, and that was Galaxy 1000 W from Enermax. Tagan TurboJet TG1100-U95 transformers, however, are connected using a different circuit design, as we will discuss in a more appropriate moment.
