Connecting an RM Series PSU to Corsair Link

 

Because the RM series uses an analog signal to send information about the fan speed and +12V rail’s load to the “C-Link” connector on the unit’s modular interface, an optional Corsair Digital Bridge is required in order to convert the analog signal to a digital signal.

The Digital Bridge consists of two pieces. Connect the four pin connector to the “C-Link” port on the RM Series’ modular interface. 

The other half of the cable connects to the first with a 2-pin and 3-pin connector.

After connecting the two parts of the C-Link cable, take the entire assembly and plug the other end into any available internal USB port.

Within Link, you should see both “RM PSU 12V A Current”, which is the measurement of the +12V load on the power supply, and “RM PSU Fan”, which is the speed the fan within the power supply is spinning. These can be logged under the “options” tab as well.  The PSU fan speed can be graphed with the other fans in your system under the “graph” tab.

If another Link compatible power supply was in used prior to the installation of the RM Series unit, an incorrect reading may show up.  If this happens, simply delete the current profile, set to default and create a new profile.

If a USB port is unavailable, the RM power supply can plug into a Corsair Link Cooling Node.  Using only the first half of the cable, plug the 2-pin and 3-pin connectors into the Cooling Node as you would a temperature probe and fan connector. 

Since the signals are still analog, Link will see the +12V current measurement as a temperature.  Simply right click on the “temperature” being reported, select “open config panel” and change “temperature” to “12V Rail Current sense”.  It is suggested that you then rename the reading so it is easier to identify within Link.

Since the fan does not send a signal until it is spinning, it will not show up in Link initially if connected to the Cooling Node.  In order to initially position and name the RM’s fan in Link, you may want to run a benchmark or burn-in program like Furmark to get the fan moving.
