A power supply device (10) comprises a casing (26), a support structure (14) and driving means (42) for selectively rotating the casing (26) relative to the support structure (14). The casing (26) houses electrical equipment (36) and electrical sockets (30,32,34). The support structure (14) is attachable to the top (12) of an article of furniture and supports the casing (26) for rotation about an axis (28), parallel to the top (12). The casing (26) can be rotated by the driving means between an operative position in which the electrical sockets (30,32,34) face upwards and are accessible above the top (12), and a stowed position in which the electrical sockets (30,32,34) are not accessible from above the top (12). The casing (26) has a protuberance (40) that extends around the electrical sockets (30,32,34) and the protuberance (40) stands proud of the top (12) when the casing (26) is in its operative position.
