Abstract
A power supply system for personal computers aims to provide an additional sub-power supply needed when a personal computer requires a power greater than what can be provided by the original main power supply. This invention provides a sub-power supply in the spare space of the existing chassis of the personal computer without removing the main power supply to augment the power supply. The starting power of the sub-power supply is provided by the main power supply. Hence when the personal computer is in the machine stop condition, only the main power supply consumes electric power. Thereby this invention can preserve a green power.
