Corsair has created a good reputation for their branded PSUs, and today they are among the most popular choices for gamers and enthusiasts. The first PSU from Corsair to find its way into our new testing lab is the RM1000, an 80 Plus Gold Certified unit with a rated output of 1000W at 40°C ambient. Given the rated power output and retail price of $169.99 after rebate, the RM1000 is understandably targeted at advanced users and gamers, and very few PCs require so much power. The target audience can be quite demanding, however, and a simple 80 Plus Gold certification is not enough to entice such users, so let's see what else Corsair has up their sleeves.

The RM series PSUs are optimized for silence and there are currently six models, ranging from 450W to 1000W. That makes the RM1000 the most powerful model of the series but it also is significantly different from the less powerful models as well. In fact, it's almost entirely different. The 750W and the 850W models come from a different ODM, as they are based off of Chicony Electronics designs, while Channel Well Technologies (CWT) supplies the other four models. As such, the RM1000 and the RM450/RM550/RM650 are all based on a CWT design, yet the RM1000 we're looking at is based on a different platform than that of the lower wattage models.
