Most power supplies have a switch that allows either 220 or 110 volt input. 220 for most European countries and 110 for the rest. You need to find out what voltage is used at your location.
Good luck,

I currently live in Korea and am planning on buying a computer. This could be a tough one, but I wonder if there are any power differences between Korean computers and N.American ones. They do have different outlet voltages so this worries me. Korean dealers have been no help, maybe someone back home can.
