Corsair RM650 Power Supply Review


Corsair RM650 Power Supply Review Introduction

Corsair is perhaps the most active company in the PSU market this year, which may be slightly ironic, as they originally were a memory manufacturer that diversified into the PSU market just a few years ago. Apparently, the tens of products which they have been marketing via their six PSU series were not enough, leading Corsair to develop a seventh, new series. Today, the companys new power supply series, the RM, is a fact, bringing 6 new units into their already crowded power supply ranks. The smallest power supply of the series starts at 450 W and the most powerful version reached up to 1000 W. Today we are having a close look at the RM650 which, as the name implies, is the 650 W version.

The company claims that the new RM power supplies are optimized for silent operation, yet that does not mean that being quiet is all these units are good at. A simple look at their specifications and an advanced computer user can identify many interesting features; a fully modular design, an 80Plus Gold certification, a single 12 V rail design and Corsair Link capabilities are just a few. Furthermore, the MSRP prices of the new units, as they can be seen in the table below, are very interesting to say the least.















According to the table above, the new RM units end up retailing cheaper than not only the high-end HX series but the mainstream TX series as well, which perhaps is an indication that other series will be receiving price cuts or end to exist.
