Abstract

The invention discloses a computer host. The computer host comprises a power supply, a cable wire and a front input / output board, wherein first and second voltage transmission pins of a first connector transmit a voltage of a first type output by the power supply to a second connector through the cable wire; and third and fourth voltage transmission pins of the second connector are used for supplying power to a USB interface on the front input / output board. According to the computer host, a voltage drop of a supply voltage between the first connector and the second connector can be effectively reduced, so that the power supply efficiency of the front input / output board is further improved.

Description

technical field [0001] The invention relates to a computer host. Background technique [0002] With the rapid development of computer technology, the Universal Serial Bus (USB) technology has become a widely used interface technology, and the power supply part of the USB interface has attracted more and more attention. The minimum power supply voltage allowed in the USB system is specified in the USB design specification as 4.75V. [0003] When the computer motherboard is in the S0 state, the front panel on the host computer with USB 2.0 interface is connected to the Front Input Output (FIO) board through a cable, and the voltage of +5V_USB is transmitted to the front input and output board USB interface, thus completing the power supply of the USB interface. However, the power supply voltage is severely attenuated on the cable used to connect the front panel to the front I / O board, resulting in the voltage provided by the front I / O board may be lower than the minimum powe...
