OCZ ZS Series 550W Power Supply Review

OCZ are using a Globe fan, the RL4z B1352512M. This is a popular choice among manufacturers.

This power supply seems to be a Sirfa design. It is a basic design, but one that has been used now (in various forms) for many years, with a lot of success.

The first stage of the transient filter uses two Y capacitors and a single X capacitor. There are two rows of heatsinks ensuring adequate cooling reaches the components. The primary capacitor is Panasonic, and rated to 85c. Secondary capacitors are Chemi Con, which is an improvement over the previous generation. The overall design is basic, but clean throughout.
