Description of the Invention: [Technical Field] The present invention relates to a power supply, and more particularly to a design for outputting a maximum DC power supply external electronic device even when the computer is in a shutdown state. [Prior Art] A power supply is installed in a general computer mainframe. Its main purpose is to convert AC power into a stable DC power supply with different voltage levels to provide various devices in the computer mainframe (such as a motherboard, a hard disk drive, and a compact disc). 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.

But today's personal computer applications, in addition to the use of operating systems and other applications software program operations, but also include the electric parking machine _ weaving single riding on the external electronic devices, such as: wonderful eight, night light, use The disc player panel directly plays the music cd, uses the interface to charge the PDA, the mobile phone, etc., or observes the temperature and humidity of the small liquid display installed on the casing, and the xinxin t has a luminous effect design, and most of them can only be used. Under the boot, the above functions can be achieved, or the power limit is used; the power supply 1 provides the DC power output under the computer shutdown state; however, the maximum wattage provided by the second and second cranes is lower, and the number of voltage output groups is lower. When there are few external electronic devices with high power, the power that the standing power system can supply cannot meet the needs of the user. [Summary of the Invention] The main purpose of the 屯吉2 is to provide a power supply that can output a straight and horizontal pen source to provide electronic device connection after the computer is turned off. ^ (4) used by the electronic device to make the place, Providing the external/guar source is still the maximum power that the power supply can provide (only 1 right main power supply (with the shape of the main power money reserve power pure ^,,,, (4) on 34 purposes, this hair _ The feasible technical solution includes: · Power supply 5 200813691 Supply power control architecture, including a main power system for converting external power source into DC power, and - normal electrical connection to the main power system and normal state - DC An electric drive power opening and closing unit, the power opening and closing unit is recorded from the electric shutdown and the computer shutdown signal, and is configured on the DC power transmission line for driving the electronic device to have at least one with the power After the connection switch, the + knife change switch receives the computer service signal as a closed circuit state, so that the direct machine power is transmitted to the hybrid, and the switching relationship is connected to (4) the electric signal is in an open state. The DC power transmission Langmu electronic device can not be affected by the electric machine, and can continue to output DC power when the computer is turned off, supply the power required by the external electronic device, and even if the computer is in the off state, the external output terminal provides The DC power supply (4) also supplies the maximum power or total power that can be supplied.
