Introduction

Corsair are renowned for their RAM modules and have also built a strong catalogue of hardware components in other sectors, including power supplies. The HX620W unit is the latest and greatest Corsair unit, a very good enthusiast power supply which has survived for many months without revisions. Today Corsair is taking a different approach with the release of the VX450W and VX550W units, which are designed with optimal value in mind, not extreme performance. The big question, "So is it any good?" will be answered today.
