For the Plus (or earlier) you either need the 220v version, or a step down transformer. Another point: "switching power supply" does *NOT* mean that it automatically switches between different input voltages. It refers to how it steps the volts down to what your ICs want. It does just so happen that it is easier to make switching power supplies accept liberal input voltages, than with convertional supplies, but that is not how they get their name. There are plenty of "switching power supplies" which will go up in smoke if you plug them into 220v. Like the US Macintosh Plus power supply, for instance...
