If I bought a gaming pc in America (110v) and brought it back to NZ (240v) can I buy a different power supply to make it work?

If I bought a gaming pc in America (110v) and brought it back to NZ (240v) can I buy a different power supply to make it work or do I need to get an adaptor or transformer?

EDIT: As below, your psu likely already supports 240V. Check the "AC Input" section of the sticker on the side. 

 

You can buy a different power supply and it'll work just fine, although many power supplies will have a 110V - 240V switch, so check yours first. (Read the manual too.) 

 

Alternatively, if you're at all electrically inclined, 110V and 240V power supplies are nearly always identical, except they use different taps off of the main transformer, so open it up, find the other, unused tap, then connect it to the plug. 

 

But only do that if you know how not to die when trying something like that.

Yes and no, sometimes you need to but sometimes you don't. Just check the input voltages of the specific power supply.

Oh yeah that too. The closest PSU to me supports both voltages so as long as you have the right cord you're fine.

Any PSU that supports 110V will support 240V. That's not always the case the other way around. 

If there is a switch on the backside of the PSU, to switch between 110V and 240V, you should replace the PSU anyway.

as long it is a bivolt psu you're fine, here in brazil it changes 110v to 220v depending the town you're at like literally, it's a mess.

If you got a decent one with a good PSU that is not needed as all decent PSU have universal Input, so they detect the input voltage and adjust to it internally, you do not need to do anything.


Just look at the Label of the PSU, if it states something like 100-240VAC, you're fine.

If it does something like 100-140V and 200-240V you are not...
