Vario self-drive Corsair has grown into a huge company over the last several years, and they are still constantly expanding on all areas they participate in. Especially their PSU portfolio has expanded rapidly lately as we saw Corsair release one line after another, which put the competition into a really uncomfortable position. The fresh RM line is, according to Corsair, optimized for silence, and our experience with the RM750 and RM850 units we already reviewed a while ago confirms just that since both aforementioned units registered very low noise output throughout their entire operating range. We would also like to remind you that the RM750 and RM850 units are made by Chicony while all other RM PSUs are made by Channel Well Technology (CWT), an OEM Corsair has cooperated with successfully for a long time. The RM650 is then based on a different platform than its two bigger siblings, and we are really curious to see how it will perform.
