A wireless-controlled power-saving apparatus is disclosed. The apparatus particularly includes a power-saving control strip and a wireless power-detection controller. The power-saving control strip has a master socket and at least one slave socket to be controlled. The strip further includes a receptacle for containing the wireless power-detection controller. More, the wireless power-detection controller connects to an external host for detecting the performance thereof. When the external host boots up, the wireless power-detection controller controls the slave socket to be powered. Or otherwise, when the external host shuts down, the wireless power-detection controller controls the slave socket to be disconnected. Thus the invention achieves the sockets mounted on the power-saving control strip to function a wireless master-slave-correlation operation.
