Using USB Port As A Power Supply - Connecting USB Devices To The PC

Can connecting electrical devices like USB fans, LED lights, and other items that require a power supply, using the USB as a power source, have an adverse effect on PC functions, or shorten the life span of any of the components of the PC, or in the network? Will the step-down transformer in the power supply be subjected to an overload? Since the USB port functions in multiple ways like conveying signals from the mouse, and transferring pulses from the router, I was wondering if over usage of this port as a source of electrical power would in any way hinder PC functions ... ?
