[SOLVED] Using 240V (230V) PSU on 120V Grid

[alphadelta]

I am relocating from the Australian power grid to the US power grid, and I'm wondering if it's necessary to buy a new power supply once I arrive.
The power supply in question is a Cooler Master MWA White 650W (230V).

I've looked around and couldn't find too many decisive answers, and the documentation on the Cooler Master website didn't shed any light on the matter.
Is it possible (or even safe for my components) to run this PSU on a 120V grid?
If it is possible, how do I do it? Do I buy a new cable, or a transformer? A new PSU of the same model is <$100, so is it even worth trying to use a PSU from another region?

Also, if anybody happens to have any advice for travelling internationally with a desktop tower, please let me know.
Thanks!

You can't use a 230v PSU on a 120v grid. You need a new full range PSU.

people are combining two 120v grids into 240V, theres advantage to it, 240V draws less watts
but there are also plenty of PSUs which have 100-250V @ 50/60Hz coverage making it any country compatible

Well -- That answers that, thanks for the help!

if the PSU says 100-240v on the side of it then it will auto see the voltage and run at 120v american

Also depending on where you are staying, if you own the home, you can put int a 240v breaker and make a dedicated outlet for the computer.

That seems an awful lot of work for PSU that isn't that good in the first place!

That's not even remotely close to how it works.

Should have worded it better....put in a double pole breaker...... That would involve pulling a brand new wire from the power panel all the way to the dedicated outlet.

Correct. But then you would need to install a 30amp receptacle and would not be able to plug in your PC.

20 amp would be more then enough, and guess what..... they make a cord for the outlet LINK . Since no one make a C13 that handles 30 amps that would be out of the question for a 30 amp outlet, unless they are changing the plug on the back of the PSU with the new ATX 3.0 standard.

Also when you move up in voltage it uses less amps, case in point my EVGA 1600w G2 110v 17A 240v 10A


Looking at the new ATX 3.0 standard you might have to have a dedicated 240V outlet just for the PSU, Some of the newer 4080/4090 GPUs will use up to 600w by themselves with the new 12pin +4 socket.
