We would like to thank Corsair for supplying the review sample.
It hasn't been long since we reviewed the Corsair RM850 unit, and it is now time for its smaller brother with only 750 W capacity but all the features of the bigger unit. Those familiar with the PSU market will have probably guessed that the RM750 is today’s test subject. Constantly releasing new, to the competition intimidating models, Corsair has been very active lately, which pleases consumers because it gives them a broader range of choices. The fresh RM series is situated below HX and above TX units, offers Gold efficiency, a fully modular design, and an ultra-quiet operation. Corsair also decided to release a PSU series that focuses on producing as little noise as possible with the RM series, and they really did conduct a ton of research to make sure these new units are noise-proof. Considering the astonishing results their RM850 achieved in our tests, we can truly state Corsair’s efforts in this area to be noteworthy.
The RM series consists of six models with capacities ranging from 450 W to 1000 W. Four of these units are made by Corsair’s favorite OEM, Channel Well Technology, while the 750 W and 850 W models are made by Chicony, an OEM we haven’t come across in our reviews yet. We don’t know the exact reasons that led Corsair to Chicony for the making of the two mid-range models, but they were apparently important enough to make the switch.
The RM units use older, trustworthy analog circuits that still make them somewhat compatible with the Corsair Link software only fully utilized by the digital AXi units, but you have to get the optional Digital Bridge to monitor +12V current output and fan speed because Corsair chose not to include the Bridge in the bundle. Doing so would have raised the final price, yet some of you will appreciate saving some money while others would have preferred it if Corsair had included the Digital Bride for a small price increase.
