Useful for CM owners without a-rgb connectors, the USB cable to connect to the internal USB port of the CM could be provided, this last one allows to control the box from the Master Plus software, because the purpose of this purchase is to be able to control an a-rgb peripheral without having the ports on the CM but they provide a cable to connect to an a-rgb port!
The software provided by Cooler Master does not include all the possibilities available on the case directly, especially the control by the thermal probe.
9/10 because it does the job of being able to control an a-rgb perif for a small price, for my part ( Cooler Master A-RGB GPU Support Bracket ) without having the connections on the CM nice the fact that it is magnetic that allows to fix it in the case easily.
