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 company's 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.
