Also, wouldn't PAL to NTSC signal be an issue as well? The TV will probably have a different signal than the console, so you might need a converter for that? So in my experience, no, the US power supplies weren't capable of handling international voltages such as 230-240V.

At 0:33 in the video you get a brief glimpse of the label on the unit, which reads “AC110V 12VA 50–60Hz”. That is the input voltage the unit is rated for. Strictly speaking, even 110V in the US would be out of spec and nothing is guaranteed here, but that might still be within the tolerance margin. However, 230V is more than twice that voltage. One thing is that, is it safe to use a Japanese N64 in American due to the different amount of voltage the two countries get? Switch-mode power supplies can be built for a much wider range of input voltages (90-264V is common as this includes all mains voltages used globally, complete with tolerance for broad specifications), but they can also be built for a narrow range, or have a switch. They should always be labelled, sometimes in tiny moulded writing.

No he is using a UK N64 in the US/Canada. Which does seem to imply that voltage might be an issue. Your system is not getting enough power due to being on 110 volt instead of 220. Usually you can not use any power supply outside the input range it's designed for. Multi-range power supplies will give you a rating of "Input Voltage 100..240V" on it's label. If they have dedicated input voltage rating then your input into the device should really be at that rating. You should always look for a power transformer converting your grid voltage to the right one for your device if you want to use it. There are some power transformers out for your purpose, depending at the power rating something like this here might be right for you:A friend and I imported a couple of US units to New Zealand so that we could play US region games. As an aside, because the power supply was a removable module, we could slot the NZ power supply into the US unit and play US games, but they still put out NTSC and so ran at a different frame rate to the NZ region versions.
