A computer motherboard includes first and second peripheral interfaces, a switching interface, a switching card inserted into the switching card, and first and second central processing unit (CPU) sockets. The switching interface is placed between the first and second peripheral interfaces. The switching card includes first and second interface. Pins of the first interface of the switching card are interconnected, and pins of the second interface of the switching card are interconnected. Connection between the first and second peripheral sockets and the first and second CPU sockets is adjustable by selectively connecting one of the first and second interfaces of the switching card to the switching interface.
