If someone bought a PC in the US, and wanted to bring it to New Zealand, what would they have to do to get it to work? NZ runs 240V/5A. I really don't know much about electrical things, what does the US use?
we use 120v. almost all power supplies have a small switch in back to select whether it will be using "115v" or "230v". just make sure the switch is set accordingly before firing it up or else you might have a problem.
