Dell PowerEdge R NVdia power

​I would appreciate your feedback on an issue ;details:​

​We’ve installed a NVidia Card K2 on a PowerEdge R server and we can see the card at the BIOS. ​

​NVidia drivers are installed and the card can be seen by the Operating System, including config options (Full GPU pass-through, various vGPU options)​

​Now when we’re running the nvidia-smi command it results in the lack of power message, this means that we can’t actually use the card. We might be missing Power Cables for GPUs? Any idea?​
