Abstract: The present invention provides a computer system, comprising: a plurality of power suppliers; and a plurality of mainboards, each of which is electrically connected to the corresponding one of the plurality of power suppliers. Each mainboard comprises a switch module for generating a switch-on signal; a control module for receiving the switch-on signal and generating a power enable signal according to the switch-on signal; and a cascade module, electrically connected to the power supplier relative to the mainboard and the control module, for receiving the power enable signal, wherein the cascade module of the respective mainboard electrically connects to each other, and, when the control module of any mainboard sends out the power enable signal, it will be transferred to the other mainboards via the mainboard's cascade module, so that the plurality of power suppliers can provide power to the corresponding mainboard to implement the mainboard's booting synchronously.
