Description of the invention: [Technical field to which the invention pertains] There is a type of electric secret for this meal. In particular, the design of the external electronic device that can output the maximum DC power supply in the state of being brewed. [Prior Art] - The computer host towel green is equipped with a power supply II. The main way is to convert the alternating current into a stable DC power source with different electric dust to provide computerized tissue devices (such as motherboards, hard screws, and optical discs). Machines, etc.) The required voltage is used, and the early main design method was to supply current to various components in the computer system when the power supply was turned on. The current mainstream design architecture of the ATX specification is t, and its thief--in addition to the DC power (3.3V, 5V, 12V) provided when the computer is turned on, it has the computer to provide the computer regardless of whether the computer is turned on or off. The host starts the power standing system of the power. However, in today's personal computer applications, in addition to the operation of the operating system and other application software programs, there are many external electronic devices that can be operated separately when the computer is turned off, such as La. Eight, small night light, use the CD player panel to directly play music CD, use USB " face for PDA, mobile phone charging and other devices, or observe the temperature, sacrifice, time displayed on the small LCD screen mounted on the case Waiting for information, or enjoying the dazzling case with luminous effect, etc., all of these applications can be operated separately without the operating system being activated, but most of the existing power supply 1^' can only be 1 under the system boot state. To achieve the above functions, or to use the power supply's standing power button to provide DC power output when the computer is turned off; however, the maximum wattage that can be provided by the normally injured power system is low, and the number of voltage output groups is small. When the user wants to connect to a higher-power external electronic device, the power that the power system can supply is always: that is, it cannot meet the needs of the user. SUMMARY OF THE INVENTION The main object of the present invention is to provide a __ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The maximum power (only the main power system) or the combined power (with the main power system and the standing power system in parallel) provided by the power supply can be implemented according to the disclosure of the present invention. Contains: _ kind of power supply 5 1333140 2 〇 the maximum power that can be provided. Please refer to "Fig. 3", which is another invention of the present invention - the invention can be fulfilled - the riding force of the material is turned, as shown in the figure: The electrical connection of the external power source (4) is replaced by the main power of DC power == = The power system 70, the standby power system 7 〇 output DC power is used to ^ _ power on and off early 30, and the power opening and closing unit 3 该 wheel the main power secret 20 and the standing power machine news - computer Shutdown signal, flow power, at least - main power secret 2 () | ^ connected to the external power source G and converted to straight 3 〇, 々 一恭2: output DC power parallel drive the power opening and closing unit
