Abstract:
1. A power supply to provide operation power for cooling fans to transform an AC power to a DC power comprising at least a non-stop power system that transforms the AC power to the DC power in normal conditions and a main power system that transforms the AC power to the DC power when the power supply is in an ON condition to supply a computer for operation; wherein the non-stop power system outputs the DC power to a remote switch control circuit in the normal conditions that set the computer in an ON or OFF condition, and to a fan actuation control circuit to drive a rear end cooling fan, the fan actuation control circuit and the remote switch control circuit being bridged by a cooling delay unit which receives a computer OFF signal output from the remote switch control circuit and outputs a first signal to drive the cooling fan to continuously operate for a period of time.
