Well, there are 4 kinds of PSU's:
- 220volt only (safe to use for you at a 220volt line)
- 115volt only (don't use this one - USA only)
- 220/115 volt PSU with a physical switch on the back of it

- 220/115 autoswitching PSU (most A-brand) PSU's like Coolermaster/Antec/Zalman/etc
But if a PSU shows 115/220 on it's label, you're safe!
