Mac Pro - universal power supply?

Hello all - wanted to ask a quick question which I BELIEVE I know the answer to, but wanted to make sure.

Currently using a Mac Pro here in the US but may be relocating to the UK next year. While I know PCs (cough) have dual voltage power supplies which can be toggled via a small switch on the back, the Mac Pro lacks no such option. The tech specs suggest it has an auto switching dual voltage supply though, so am I correct in assuming that if I bring the Mac Pro with me, it'll work over there without issue (well, after purchasing a new power cable, of course)
