A computer system with a non-support hyper-transport processor and a controlling method of a hyper-transport bus thereof. The computer system includes a system management controller, a Northbridge, a hyper-transport bus, a central processing unit and a power management signal line. The Northbridge is electrically connected to the system management controller through the hyper-transport bus. The central processing unit is electrically connected to the Northbridge, and the central processing unit does not support the hyper-transport bus. The system management controller outputs a power management signal to the central processing unit and the Northbridge through the power management signal line so that the hyper-transport bus changes from a first working frequency to a second working frequency, and from a first bus width to a second bus width.
