PC Power Supply (in Japan)

I have a desktop computer, built in the U.S. So it uses, obviously, a U.S. power supply.

Unfortunately, the power supply died. Now I'm curious - what's the difference between a U.S. Power Supply and a Japanese Power Supply?

I already live in Japan and would rather not order a power supply from overseas (to put it simply, I don't have a credit card or U.S. bank account so it's a real hassle ordering anything).

Is it possible to buy a power supply that would work for my desktop computer here?

Thanks!

The important thing is the power that the PSU delivers to the hardware. The voltage will be the same, just make you get one that can provide enough watts to run the system.

(Short answer: yes, it's fine)

PC power supply units are sold in any PC part shops.
They are same worldwide.

Some PC power supplies are switchable (see the switch at the back) 110/240V. These will work anywhere. Make sure to select the sorrect voltage.

Some just have 110V on them, and they will work in Japan (and the US)
Some just have 240V on them, and they will work in Europe, Australia, etc.

Thanks a ton, to all the responses. Simple, helpful, and to the point. :)

Standard voltage in US is 117v while in Japan, it is 100v. Some US electronic appliance won't work probably or won't last under this changes. The computer itself needs only 5v to run and that's what a PSU should deliver no matter the input power is 100/120/240v.

In your case, buy a new PSU in Japan to replace the dead one. My experience is that the heavier the unit, the better it is.

This is not correct. PCs require 5V, & 12V, plus the the CPU voltage. If you have a 100/120V power supply, and plug it into 240V, it will blow up. If you have a 240V power supply, and plug it into 100V, it will not work.

As I said, they come in three different types: 110V, 240V and 110/240V switchable. These are switch mode power supplies, and they will work on an input of +-10-15%. The 110V supplies will work for 100V through 120V. This will not affect the output voltage, since it's switch mode.
