We decided to disassemble this power supply to see how it looks like inside, what is the design used 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 on the next pages we will discuss in details the quality and rating of the components used.

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.
