Official Nintendo Power Supply for your N64. These are from Japan but have been tested and cleaned and perfectly safe use in North America for your N64. Just to be clear, here are images (from the links above) to show that this is possible (if forced). 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. Plugged it in (with a plug adapter) switched it on that lovely red light comes on BAM No Signal. Looked it up people saying yeah those old AV cables are abit temperamental, so bought a new one plug it in....still nothing.

While I have seen power supplies that work outside their intended mains voltage (an early 2000s cell phone charger rated for 220–240V, which worked fine on 110V – the other way round is less dangerous), this power supply does not seem to be one of them. Sound Errors Sometimes when I play the game it makes these weird noises like ''Yaaaaaaaaaaaa" or ''Mmmmmmmmmmmmmmmm" tEhhhhhhh" and then it freezes with those noises still being there. Let's see, you're plugging a power supply needing 220 volts into an outlet that only provides 110 volts using a cheap travel adapter that only adapts the physical shape of the plug and converts nothing voltage wise. I'm going to guess that this is the issue causing you problems.At 0:54 you can see the entire PCB. The labeling in the top-right corner of the PCB reads “2.5A 125V 5A 125V”. So there are components on the PCB which are designed for 125V, but not for 230V. And finally, why would the guy in the video go through all the hassle of gutting a 100V power supply and replacing the circuitry with that of a 240V one, when he could simply attach a UK mains plug to the Japanese unit? Now as for PAL SYSTEMS in America and elswhere, you would need an ADAPTOR anyway because the PLUGS ARE DIFFERENT.

Looking at prices its cheaper to buy a US power supply than a step up converter. Just to clarify the PAL/NTSC signal issue I have a smaller samsung tv I shipped over when I moved that I have as a spare, that's been working fine with other retro consoles.

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.Note: Even when I play the original Super Mario 64 and other games, it freezes randomly too and does those three things I've listed above. As for “installation”– You basically just plug it in. You could choose to gut your existing N64 PSU and use its plastic as a shell, but I much prefer this method: Simply press the pins on the new PSU right over the power supply pins on the N64; With the N64 plastic case on, it will only fit in one orientation (shown above), so there’s no chance of getting it wrong: But I was thinking about buying a new Nintendo 64 online, but if I do that and it still does the same thing then that'll be a waste of money.
