摘要：
A computer motherboard includes a number of peripheral device interfaces, first and second voltage output terminals, and a number of power supply circuits corresponding to the S peripheral device interfaces. Each peripheral device interface includes a first power pin and a second power pin. Each power supply circuit includes a delay circuit, and first to third electronic switches. The delay circuit controls the first electronic switch to be turned on after a delay time. The delay times of the power supply circuits are different. The second and third electronic switches are turned on in response to the first electronic switch being turned on. The first voltage output terminal is connected to the first power pin through the second electronic switch. The second voltage output terminal is connected to the second power pin through the third electronic switch.
