Abstract: A power supply cable outlet angle adjustment structure aims to overcome shortcomings of the conventional power supply that cannot adjust cable outlet angle to mate connecting electronic devices. The power supply has an opening on a body to allow a power cable to be threaded through and a pivotal turnable adjustment member connected to the opening. The adjustment member has a cable outlet to allow the power cable to be drawn out. The power cable can be pivotally turned synchronously with the adjustment member at a selected outlet angle to mate different installing locations of the electronic devices to facilitate connection between them.
