What is proprietary power supply?

Answer 1

A proprietary power supply refers to a power supply unit that is specifically designed for a particular brand or model of device, often incorporating unique connectors or specifications that are not compatible with standard power supplies. This can limit users' options for replacement or upgrades, as they must use the manufacturer's designated power supply. Such power supplies are common in certain electronics, like laptops and gaming consoles, where optimized performance and size are critical. While they can ensure reliability and safety, they may also lead to higher costs and less flexibility for consumers.
