Abstract:
1. A power supply system for personal computers to transform city power to multiple DC power of different potentials to be used for operation of a personal computer, comprising: a main power supply which is located in the personal computer and has a main power system to perform power transformation for the operation of the personal computer and a non-stop power system to provide a starting power supply in normal conditions to the personal computer, the main power supply having a first input end connecting to the city power and a first output end to output first DC power; and a first sub-power supply which is located on a chassis of a side panel of the personal computer and has a second input end connecting to the city power and a second output end to output second DC power, the first sub-power supply having a first sub-power system to perform power transformation for the operation of the personal computer, the first sub-power system being driven by a starting power which is provided by at least one output first DC power from the first output end of the main power supply, the main power supply being started to output the first DC power then to start the first sub-power supply.
