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.

    Dear Corsair, I both two months ago the Corsair 850RM power supply. I've received only the C-link cable without any Analog to Digital Bridge cable. Please be so kind and let me know from where can I purchase this. I have and use also the water cooler H80iGT from you, the Corsair Carbide Series Air 540 High Airflow ATX and all the fans are Corsair. Thank you.

    all that is very useful, especially when one can not buy the "Corsair Digital Bridge" here in Poland. I will think twice about buying Corsair PSU equipped with some special additions next time ;(

    The box seems to indicate you supply the Corsair Link cable with the PSU although after much trouble I can now see you do not. This should be made clearer on the box and in the description of the unit. Also tried to open a customer support ticket and it simply would not allow me to proceed without a valid part number. I tried RM850, RM-850, and 850 as a part number but it would not recognize any of them and your product part number locater did not seem to know that you sold a RM850 either. This needs to be fixed. Also where the heck is the customer support phone number? It seemed to indicate you offered chat and telephone support but I could not locate it anywhere on the page.

    Very bad marketing move. You release the RM PSU series in Europe, but cannot buy the Analogue to Digital Converter anywhere!
