Introduction

2-Banner.jpg

The Corsair RMx Series currently includes five models: 1000W, 850W, 750W, 650W and 550W. And the 850W model is available in either standard black or special white. The RMx series is very similar to Corsair’s RMi series but with the advantage of lower cost due eliminating the digital Corsair Link interface and staying with 80 Plus Gold level efficiency. Like previous versions, all of the RMx Series power supplies are designed by Corsair and built by Channel Well Technologies (CWT). We will be taking a detailed look at the RM850x PSU (standard black) in this review.

The RMx Series power supplies are equipped with fully modular cables and optimized for very quiet operation. RMx Series power supplies incorporate Zero RPM Fan Mode, which means the fan does not start spinning until the power supply reaches a moderate load. The cooling fan is designed to deliver low noise and high static pressure.

The Corsair RMx Series is built with high-quality components, including all Japanese made electrolytic capacitors, and Corsair guarantees these PSUs to deliver clean, stable, continuous power, at ambient temperatures up to 50°C. And last but not least, the RMx series comes backed by a 10-year warranty.
