Electrical note: The Whatsminer M31S+ has a power consumption of approx. 3.4 kW, which exceeds the continuous load limit of a 230 V / 16 A circuit (~3.7 kW). Have the device connected to a dedicated CEE socket by a licensed electrician – via an IEC C19 cable. Standard household sockets are not suitable for this load.
Please note: The miners are used and have been used in mining farms for varying lengths of time. There are therefore also visible signs of wear.
