A USB 3.0 host with low power consumption includes a super speed circuit, a non-super speed circuit, and a control module. The super speed circuit is used for transmitting data at a first transmission speed. A default state of the super speed circuit is turning-off. The non-super speed circuit is used for transmitting data at a second transmission speed, a third transmission speed, or a fourth transmission speed. The first transmission speed is faster than the second transmission speed, the third transmission speed, and the fourth transmission speed. The control module is used for detecting whether a USB peripheral device is connected to the USB 3.0 host, and controlling turning-on and turning-off of the super speed circuit.
