What you are talking about is the power supply as a whole. A transformer designed for use on the mains is by itself only designed for one specific voltage and cannot normally handle two different mains voltages UNLESS it has extra taps\winding and a manual switch to allow it to be used on either.

Switchmode power supplies can have automatic voltage selection but not all of them actually do. The older they are the more likely they are for only one input voltage.

1254908 2012-03-02 04:18:00 Hi guys I know this is an old thread but I have one other question.
Some PSU's have red switches on the back of them, they change the voltage let into the PSU to either 110V or 240V, something like that. Am I right?
So if I bought one from the states I could flick a switch and it should be ok?

1254909 2012-03-02 05:39:00 If it actually has a switch then yes! Snorkbox (15764)
1254910 2012-03-02 07:23:00 Most newer ones don't have the switch because they don't need it, they can handle either voltage and auto-switch by themselves.

If this is the case the label will show this.
