Printed Circuit Board (PCB) Power Connections: In electronics, a printed circuit board (PCB) is a board that provides mechanical support and electrical connections for electronic components. Power board connections on a PCB would involve connecting power supply lines, such as voltage inputs, ground connections, and power distribution traces to various components on the board.

Power Strip or Surge Protector: A power strip or surge protector is a device that allows multiple electrical devices to be plugged into a single power outlet. The power board connection in this case refers to the connection made between the power strip and the wall outlet, as well as the connections from the power strip to the individual devices.
