Corsair CS450M Power Supply Review


Corsair CS450M Power Supply Review Introduction

Corsair has been a very active player in the PSU market the past year, announcing release after release, bringing several new power supply units into the market. A few weeks ago, the company has announced the release of the CS-M power supply series, a series designed for basic and midrange PCs, bringing the number of the power-related products that they offer even higher. Even though the series is designed with value in mind, Corsair claims features and performance that would significantly outperform their previous mainstream series, the TX. Today we are having a close look at the CS450M, which, as the name implies, is the 450 W version and the least powerful unit of the series.

From the table below, we can see that the 450 W version has an MSRP of $89.99 and can be found online for $89.99 shipped. Although we cannot compare that directly to the older TX series, as the least powerful TX series unit is a 650W version, the TX650M has an MSRP of $129.99 and the CS650M an MSRP of $109.99. This means that the new CS series not only is cheaper by $20 but it also is 80Plus Gold certified, a leap forward than the TX series which only meets 80Plus Bronze standards. What about the rest of its performance aspects though? We will find out in this review.
