Power Adaptors / Famicom Power Supply

[133MHz]

It means that your Famicom/NES won't work with it, and if you leave that plugged in for too long you'll burn the voltage regulator and other things of your RF board.

Long story short: Reverse polarity damages your NES/Fami. (it has some reverse polarity protection, but if you leave it in that condition too much time they'll eventually overheat and short).

I'm looking into grabbing a Twin Famicom, but the one I'm looking at has no AC adapter.  Is the unit compatible with another system's AC adapter?  If not, what are the specs on it so that I can find one myself?

I don't know about compatibility, so I took a photo of my Twin Famicom AC adaptor for your reference. 

[Gao]

Thanks for that.  So does this mean I need an adapter that can handle 1.25A, or could I get away with one that was rated for 1A?  A quick glance over Walmart and Radioshack's websites found nothing that could handle anything more than 1A.

It'll work just fine.

Hello,

I have just bought a Twin Famicom system, looks nice and everything  - problem is I live in the UK (Britain) so it won't work with the power from my wall socket.

I have a step-down adapter which works with many other Japanese systems but not the Twin Famicom. When I plug it all together (console, power supply, step-down adapter) and press the power button the power light comes on for a split second then goes away, this can't be right can it?

Does anyone have any ideas why the other Japanese systems work with the adapter but not the Twin Famicom?

Any help would be appreciated as I would like to use the system but don't won't to blow my console and house up trying.

Many Thanks

Ross

it  means the twin is broken

Test the AC adapter in another system or with a multimeter to see if it is the culprit.

it  means the twin is broken, duh

No need to be an ass, kite. Not everyone knows the ins and outs of this stuff.

[kite200]

the one thing I can think of is that the AC is fried but not the console


Is that even possible?

[keiffer01]

Yeah it's possible. It happened once to my Atari 2600.

I have three power supply related questions:

1. I bought a Super Famicom from a used video game shop and the power adapter it cam with was a Sega adapter, I believe from a Genesis, although it may be from a Mega Drive.

My question is, will this cause damage to my console in the long run? I have already played it a little and everything seems to be working fine, but I just want to make sure.

2. Do I need a converter for a Famicom AC adapter to convert to a north american outlet?

3. Do I need a converter for a FDS AC adapter to convert to a north american outlet?\

I tried searching around some other forums and stuff but it seems like nobody had a straight answer. Thanks in advance.

The difference in volts from Japan to America is 10v which is nothing. A stepdown converter isnt needed.
As for the adaptor, I have no idea. It would be best to use a Nintendo brand HVC-02(I believe thats the model number) adaptor to avoid any issues though.

[133MHz]

1. No, it will work fine.

2 & 3. No, but some people here recommend using a 110->100V stepdown transformer. Personally I think that ~10V extra is no big deal, if in doubt, get good quality generic replacements (MW sells some good NES/FC/SNES compatible power supplies).

I bought the Famicom, and Famicom Disk System, from eBay. The Famicom arrived in good shape, with the official Famicom AC adapter. The Famicom Disk System arrived with many deep scratches, and did not include the official Famicom Disk System AC adapter, even the the add stated that it is mint, and complete. I could not get both systems to work, and while trying to get them both to work, I used the NES AC adapter on both systems, which may have ruined them. I need two AC adapters to play the Famicom connected to the Famicom Disk System, and since I do not have the Famicom Disk System AC adapter, I thought I would use the NES one. Later on, I also used the NES AC adapter on the Famicom, and I used the Famicom AC adapter on the Famicom Disk System, just to see what would happen. No signs of either sytem, frying occured. The Famicom Disk System lit up for 5 seconds, stopped, and never lit up again. I have filed a dispute with the seller of the Famicom Disk System, and I should recieve a refund. I may have to send the system back, but that's okay. I already bought another Famicom Disk System on eBay for cheap, so hopefully, this one will have no problems. I may know someone who has an official Famicom Disk System AC adapter, but if not, I could always use batteries. As for the Famicom, perhaps it still works, but I just need to hook it up properly. Also, when I opened up the Famicom Disk System, there was a screw missing, and at that point, confirmed that it was just a piece of junk, so it may go back to the seller, and I should get my refund, since I always pay through Paypal. I don't have any Famicom games, so I have no way of really knowing how it would work, but apparently, a gray screen comes on if no game is inserted, and I couldn't even get that, for my screen remained blue. So much hastle, just so I can play Super Mario Bros. 2 on the Famicom Disk System.
