for 12V 5 A you will need at least a 60VA PSU. it's usually better to go for 20% above or you'll be running it at full pelt and it'll get hot then fail and you'll need to get another.
Battery charger is probably the best bet. or a 12v lighting transformer, but you'll need a full wave rectifier to get the dc for the motor.
The motor will cope without smoothing capacitors if you want to keep cost down.
If you get a laptop PSU make sure it's 12V a lot are 19odd volts and the motor will have an in rush current when it starts. A Switchmode PSU, such as a laptop psu may not like this.
