コンピュータに制限が生じることがあった。Some PCI card type devices can supply power required for the devices connected to the card to operate to the devices. (Examples include a USB 2.0 interface card and a PCI card type hard disk drive.) When such a device is connected to a PCI card type device, the power consumed by the connected device is reduced to a PCI card type device. It must be supplied from the power supply of the computer via the PC. In addition, some PCI card type devices have devices connected to the card physically mounted on the card itself. PC equipped with these devices
In the case of an I-card type device, in addition to the power consumption of the PCI card type device itself, it is necessary to supply the power consumption of the device mounted on the card. The PCI card type device is mainly used in a desktop computer or the like. Conventionally, such a PCI card type device can be used because the power supply device mounted on the computer has a margin. However, in recent years, computers have been reduced in size, reduced in power consumption, and reduced in price, and the power that can be output from a mounted power supply unit has also been reduced. For this reason, when a PCI card type device as described above is attached, the computer may not work or be broken, or the PCI card type device may not perform its original performance or may not operate at all. There is. As a result, the selection and use of a PCI card type device that can be used by a personal computer may be limited, and the computer that can be used by a PCI card type device may be limited.

る。According to the present invention, in addition to the power supply from the power supply device of the computer (FIG. 4) or independently (FIG. 5), power is supplied to the PCI card type device from the outside. These problems are solved by supplying more electric power than can be supplied by the computer main body including the power supply device.

うようなことは起きない。When power is supplied from an external power supply,
As shown in FIG. 2, an output power Y of an external power supply is supplied to the PCI card type device in addition to the power supplied from the power supply device of the computer. Therefore, when the output power Y is added to the output power X as shown in FIG.
(Output power X + Output power Y-Power consumption A-Power consumption C)
Power can be supplied to the outside, or power of (output power X + output power Y-power consumption A-power consumption B-power consumption C) obtained by subtracting the power consumption B of the PCI card type device can be supplied to the outside. . The ratio of the output power Y from the external power supply to the power supplied from the power supply device of the computer to the PCI card type device can be appropriately designed depending on the application. For example, an upper limit may be set for the power supplied from the power supply device of the computer, and an upper limit may be supplied from an external power supply. In this case, if the upper limit value is appropriate, the sum of the power supplied from the power supply device of the computer to each device in the computer is always the output power X
Below. When the output power Y is used independently as shown in FIG. 5, the PCI card type device uses power up to the output power Y,
Power consumption B of the I-card type device was subtracted (output power Y−
The power of power consumption B) can be supplied to the outside. In this case, the burden on the power supply of the computer is the power consumption A
Since only the + power consumption C is sufficient, the protection circuit in the power supply device of the computer does not operate to stop the power supply.
