Abstract

An assembly of a power supply to a data access device inside which a 3.5-inch hard disk and a circuit are provided. The hard disk is electrically connected to a signal and power conversion unit to obtain a required voltage and signal supplied by the signal and power conversion unit. Two connection terminals arranged on the signal and power conversion unit are respectively may transmit a signal and meanwhile carry a first voltage to supply power to a circuit and its electronic parts and may receive only a second voltage or convert the second voltage into a third voltage. Alternatively, dual sets of second and third voltage are optionally received as the power supplied to the 3.5-inch hard disk and the circuit and its electronic parts for a solution to a dual-channel multi-power and signal transmission.
