Can you please explain what you mean here? A device plugged in will only draw the power it needs. It can't be "over-powered". You can certainly provide too many volts, but power (amps) is not the same.
If your device attempts to draw more power than the circuit from the power source is capable, you run the risk of over-heating the line/circuit. A properly designed circuit will have a fuse to protect against this.
