110 or 220 V for US iMac

I just bought a 27 inch iMac, it doesnt the the computer can work on either 110 or 220 V. Does anyone know whether US iMacs can work on 220 V? I only saw 110V on the electrical outlet

Mac OS X (10.6.6), iMac 27"

You'd definitely have to look closely to make sure, but I don't think anybody has made a power supply that doesn't auto switch between the two voltages in quite a long time. Usually, there is a tag on the bottom or back that indicates what power to use. Usually, Input: 100-240VAC 50/60Hz.
