it doesn't come with a power cable, but takes a standard PC or PSU power cord (3 prong).
If you live in the US you need 220/240v power so you either need to find an adapter plug for a high voltage receptacle that you might have for a washing machine for example, OR if you know an electrician you can have him run a dedicated 220v circuit for you and request a standard (or a "chinese") receptacle for it that will take the standard power cord. Just be careful to label this as a 220/240v socket since it will explode any standard device plugged into it in the U.S.
