I am still unclear here. I have already bought the PSUs. I got an APW 3++ for each miner. I am hooking up 4 S9 miners to this outlet. How is a 16AMP rated PDU enough for this set-up? Even with the right PDU, will a 30 AMP circuit be SAFE for this set-up? What cables will I need to connect the PSUs to PSD? I really just want to be clear before I take action, and I am now hearing conflicting information from the responses I'm getting. Thanks in advance!
