All arcade machines come with a so-called C13 poer cord and a EU style plug. If you need a different cable because your outlets are different then don't worry.
C13 cables are the most common cables on the market. You probably even have some laying around. Check desktop computers, monitors etc. or just stop by your local shop. For 4-6 Euro's you can get a local C13 powercord with your own style plug.
