Famicom AC-Adapter and General Power F.A.Q.

[133MHz]

Are you from Brazil? Not many countries run on dual voltage standards (not counting 220V split phase systems like the US - true either/or depending on location) and if that's the case you must find the exact voltage used in your area before plugging in a non-universal appliance.

In Brazil there is no standard voltage; most states use 110-127 V electricity (Rio Grande do Sul, Paraná, São Paulo, Minas Gerais, Bahia, Rio de Janeiro, Pará, Amazonas,…). In many hotels, however, 220 V can be found. 220-240 V is used mainly in the northeast: in the capital Brasilia (Distrito Federal) and, among others, in the states of Ceará, Pernambuco and Santa Catarina.

Not from brazil, from colombia i guess some countries of south america share that dual current, so is better if i get a universal adapter and set it up¿?

In regards to the voltage converter linked in the OP: http://www.amazon.com/VCT-VT-1000J-Japanese-Transformer-Converts/dp/B000PC4SVU

How would one go about attaching a power strip to this to power multiple components? The only power strips I know of have a ground pin, but the 100V output of that converter does not have a ground socket.

By using a 2 prong to 3 prong convertor

Most consoles and power supplies are double insulated and do not require earthing but it is good to screw in the ground point.

Hello everyone, I'm a newcomer here even though a long-time Nintendo enthusiast, who finally acquired an equally long-sought Famicom (AV-modded).

As my very first post here, I'd like to ask some advice on the right way to supply power to the console, as I'm having some unexpected issues on this regard.

I live in Europe, Italy. I tried to use a 'Universal switching' PSU with the following characteristics:

Input: 100 / 230V AC
Output (switchable): 3,0 / 4,5 / 5,0 / 6,0 / 7,5 / 9,0 / 12V DC (I set it to 9V, with the polarity configured on + C -)

Now, the problem is that using this power supply results in a distorted and rolling / blinking black and white picture, with some slight buzzing audio as well. I immediately switched the system off and I really, really hope not to have damaged anything.

I'm fairly certain that my TV supports 60hz through composite, as it's one of the latest Sony CRT panels manufactured here and every other NTSC console I've tested through composite played magnificently on it. So, I'm excluding it's a video-related problem.

Is this PSU inappropriate? And also, is it risky to make further attempts with it? I also have to remark that the plug itself on the adapter doesn't completely fit the Famicom socket, could this be a reason of concern?

Thanks in advance for any help!

your PSU is weak and can't provide enough power for famicom.

[Arren]

Thanks for the prompt answer! Now, one thing I forgot to state is that the PSU is rated at 1000mA. I thought that was enough?

[famifan]

1А for what output voltage?

true real 9V 1A is enough

the failure reason is the voltage drop on high load, such as 1A. If the voltage goes below 7V you get noise in picture and sound

try to check output voltage on such high load

I'm still getting a distorted and rolling b&w picture, after using both a more efficient PSU and a stepdown converter with the original famicom PSU. Further research seems to point to the fact that it's actually a video-related problem. I can hear the sound perfectly fine, but the video gives a distorted and rolling picture.

As far as I can gather from the documentation on the matter, it seems the video is losing sync with my (PAL) TV. Are there any easy solutions to this mess?

[ericj]

Can you force your TV into NTSC mode? Who AV modded your Famicom? I'd open it and check that it doesn't have the Makko PAL board.

[Arren]

Actually my TV doesn't have a 'NTSC mode', but it should accept NTSC signals perfectly fine, as I tested a Super Famicom with a composite lead immediately after trying this Famicom and the result was a crystal clear image.

I don't know who modded my console, I bought it off a fairly reputable vendor on eBay.

Hi everyone,

I live in Europe/UK and recently got a Super Famicom and Japanese N64. Now what i need to know is what type of adapter i should use for the two consoles?

I read the 1st post and still kinda confused... suppose for Super Famicom i can use this or this

if not, what about this ones?

And what about the N64, can i just plugin a PAL adapter?

Hope you can help, thank you

[Rosser]

Super Famicom will work with Mega Drive 1 adapter only Mega Drive 2 has reverse polarity and the plug is smaller

For N64 your either going to need a 220-240 Ac Adapter or step downlike this

Edit:check your AC adapter on the N64 it may be dual voltage 100-240 if so you're good I know some 3rd party ones are but I can remember about official ones

[P]

And what about the N64, can i just plugin a PAL adapter?

Yeah if you have a PAL N64 already you can just use that adapter. It should have 220-240v input and 12v output.
I use my PAL N64's adapter for my Japanese N64.

nvm; will place in a more appropriate thread to reduce redundancy
