All Electronics has some great deals on power supplies in a variety of voltage and current configurations. Regulated DC power supplies provide a constant voltage output when used at or below their rated current. i.e., you can use a 3 Amp power supply for a 1 Amp application. If it is "regulated" it will provide the correct voltage.
If you find a power supply with a suitable voltage and current rating, but the wrong connector, take a look at our selection of coax power adapters and retro-fit coax power plugs that allow you to change the plug size without soldering.
We also stock variable-voltage bench or lab supplies and pc mount supplies for breadboarding. For applications where regulation isn't a critical concern, we have a selection of low-priced AC-DC wall adapters, aka "wall warts," or unregulated power supplies.
