ABSTRACT:
The present invention discloses a control structure for a power supply, which comprises: a primary power system, a power switching unit, and at least one switch. The primary power system transforms an external source power into DC powers. The power switching unit is normally electrically connected with the primary power system and normally driven by a DC power output by the primary power system. The switch is installed on a DC power cable supplying DC power to an internal electronic device. Thereby, when the computer is turned off, the present invention will not be affected but can still provide DC powers to external electronic devices. Further, even though the computer is turned off, the present invention can still provide the external electronic devices with the maximum power (when only the primary power system is installed) or the total power (when the primary power system is connected in parallel with a regular power system).
