Hey guys,just want to ask I bought an Xbox from Taiwan,so is it an Asian console,or Japanese one?

There are Chinese and Korean words on the box

it should be Asian console

I think my xbox needs a step down transformer.

So is it okay if I get a step down transformer of 300 Watts?

For Xbox One anything between 200w & 300w will do.

Max rated power on XBone Power brick is around 219w

But mine is a Xbox 360 with kinect

then u can just buy the powerbrick from most of the game shop. the price is almost the same as a stepdown transformer
