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, while in the following pages we will discuss the quality and ratings of the components used in detail.

Seventeam says that this power supply has Japanese capacitors, however only the big electrolytic capacitor from the primary is Japanese (from Rubycon). All others are Chinese from Samxon. This wouldn’t be a problem if Seventeam didn’t use the word “capacitors” in the plural on the box and on their website. According to Seventeam, this was a wrong translation made from Chinese to English and the correct should be “main capacitor.”

As mentioned before, ST-650P-AF and ST-750P-AF use a different project.
