An expandable power connector module in the form of a modular power board or modular power strip 10 is described. The modular power board 10 includes a plurality of power sockets 12 provided on a base structure 14, each of the power sockets being connected to a power cord 16 for connection to a mains supply power outlet. The base structure 14 is designed to connect to one or more additional power modules and is provided with snap-on connectors 20 for physically connecting the base structure to a second power board 22. In this way, the function of the power board can be expanded to provide additional power connection and/or power conditioning features by connecting one or more additional power modules. The base structures 14 and 26 are also provided with electrical connectors for electrically connecting each of the power sockets 12 on the second power board 22 with the power cord 16 of the first power board 10. The base structure 26 of the second power board 22 may also be connected to an additional power module in the form of a battery backup module 30. The battery backup module 30 is also provided with snap-on connectors 32 on either side of an upper surface of a casing 34. Either one or both of the modular power strips and battery backup module 30 are provided with electronic switching means therein for controlling the supply of electrical power from the battery backup module 30 to the power sockets 12 in the first and second power strips in the event of a failure in the mains power supply. In this way, when the power connector modules and battery backup module are connected together they form a modular uninterruptible power supply (UPS).
