Antec CP-850 Power Supply Review

Transient Filtering Stage

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.

Antec was expecting us to disassemble this unit, as it has its logo inside the power supply.

This power supply uses two printed circuit boards, a small one with the transient filtering stage, the rectifying bridge and the PFC coil, and a big one with all other components. The solder side of each board was facing outside the power supply, so the components from the two boards were facing the middle of the power supply, making a tunnel so air could pass and cool the components down.
