I have seen a repeated confusion about AMPS from new users.
A component or device needs current to operate. LEDs, relays, motors, processors, and displays are examples of components and devices that require current (at a specific voltage) in order to operate. The current requirement of the component or device is measured in Amps or milliAmps (and sometimes microAmps, and rarely nanoAmps).
Passive components like wires, switches and relay contacts may have a current rating, usually in Amps. This is the not to exceed amount of current that that component may withstand while transporting current to the device that needs it.
Power supplies are rated in Amps. This is what power is available. As long as the sum total of the Amps required by your devices is lower than the rating of the power supply, you are good to go.
For example, this power supply (A.K.A. Wall Wart) is capable of delivering 1.5 Amps at 12 Volts DC.
