You have to check its input rating. If it has the usual 100-240VAC and 50/60 Hz on the label then usually just a plug change.
Hi so I'm going to be moving to the US in a few months from the UK. I was just wondering if that would mean I'd need to get a different psu for my PC since there's different power currents (I think that's what it called?) between the two countries, or would I just need to get a different AC cable.
The same goes for things like my monitors and xbox one.
