Abstract: A power supply converting circuit includes a multi-phase pulse-width modulation (PWM) controller, a single-phase PWM controller, some first voltage converting circuits, a second voltage converting circuit, and an electrical switch unit. The multi-phase PWM controller provides some first PWM signals and a second PWM signal. The single-phase PWM controller provides a third PWM signal. The first voltage converting circuits receive the first PWM signals to output a first power supply to a central processing unit (CPU) chipset. The electrical switch unit receives the second and third PWM signals to selectively output the second or third PWM signal to the second voltage converting circuit to output one of the first and second power supplies, such that the second voltage converting circuit selectively outputs one of the first and second power supplies to the CPU chipset.

Abstract: A computer motherboard includes a display controller, a digital visual interface integrated (DVI-I) connector, and a switching unit. The switching unit includes four first terminals, two second terminals, and a control terminal. Two of the first terminals are respectively connected to clock and data pins of a first display data channel (DDC) of the display controller, the other two first terminals are respectively connected to clock and data pins of a second DDC of the display controller, and the second terminals are respectively connected to DDC clock and DDC data pins of the DVI-I connector. The control terminal is connected to a hot plug detect pin of the DVI-I connector to detect a voltage and correspondingly control the second terminals to be respectively connected to the two first terminals connected to the clock and data pins of the first DDC or the second DDC.
