A Look Inside The ES-800

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.

The interior of BFG ES-800 looks like a mad scientist’s erotic dream: lots of circuits cramped in a very small form factor. On ES-800 the standby (+5VSB) power supply is built in a completely separated printed circuit board.

Another thing we immediately noticed was the presence of only Japanese capacitors. The primary uses capacitors from Panasonic (Matsushita, the black one), from Hitachi (the blue one) and from Chemi-Con (the brown ones), while all capacitors from secondary are from Chemi-Con.
