Power Adaptors / Famicom Power Supply

[shmuper1988]

hi sorry to reserrect a resonably old thread, but I just recently bought a famicom for the cheapest I could find, which is in a very decent condition. Only catch was, it wasnt provided with the orginal adapator for the console. I think I got the RF connector part sorted, but I am alittle bit apprehensive about using a personal ac adaptor for the power supply. as it was stated on this thread japanese use 100v range, but the power supplies here in the uk is like 220v-240v. I read on a previous thread that "so long as the out put is below 12v and above 9v, the famicom should be fine but I wana clarify with ppl whether or not these adaptors I got on me would work or just fry my console.. here the two adaptors I got and their ratings:

Binatone airlink 800
input:AC(~)240v 50hz 13W
output:DC(:::)12v 500mA
polarity: (+) - (o - (-)

alba type 8A
input: AC 230-240v ~ 50hz
output: DC 6v ::: 600mA             
polarity : (+) - (o -  (-)

(the ::: is basically a straight line with 3 dots underneth, couldnt work out how to type that part out, sorry for confusion)

I havent seen any post from uk (europe) players who own a famicom, except for 1 post but I feel I need more elaboration on what is best, I dont know much about electrics and stuff but want to see if I could get away with using these adaptors rather than having to buy the orginal 1, and then a converter.

The Binatone airlink 800 adapter should work perfectly, the other one doesn't provide enough voltage (won't cause any damage but it won't work either).

any AC Adapter with an maximum output of 12V would fit in. coz inside the famicom their is this Voltage Regulator transistor that regulates it into 5V.

Does a genesis power supply work with a famicom? Or any other power supply?

[nintendodork]

Yes, a Genesis model 1, and a TurboGrafx16 power adapter will work with the Famicom.

[EarthwormJim55]

Thank you! I will use a genesis model 1 power supply!

genesis is 9v i guess? it should still be regulated inside into 5v. so yes its compatible.

I also have shmuper1988's problem. From what I'm hearing in this thread, this will work?

"Input AC 120V 60Hz / Output DC 9V- 850mA"

I'm in the US, and I think our house voltage is different than the UK's.

Yes it works, but that particular AC adapter is terrible. Don't be surprised if it breaks after a few days or weeks. Of course, YMMV.

[MS-DOS4]

Well, maybe if I'm extra careful it will last. The power adapter I got with my Super Joy 3 TV game still works fine after 5 years of service, and that thing is super cheap. (That darn thing is currently what I use to play all my famicom games. The N64 design is so uncomfortable!)

I just got my Twin Famicom in the mail today. I have a 3rd party power adaptor that I am using to power it up. It's a Sanyo Japanese 100v AC Adaptor, with what appears to have negative center polarity.


I do realize that the Twin Fami calls for a positive center adaptor. I didn't notice this until after I had played it for a total of probably 2 hours off and on throughout the day. I had no problems with powering it on, but now I'm not going to use it again, because I found this info out. Obviously, I shouldn't use this adaptor again, to be on the safe side, right?

[133MHz]

Did it come with your Twin Famicom? If so, I bet that it was modified to output center positive polarity by the seller, since it wouldn't work at all with reversed polarity. If you have a multimeter you can eliminate all doubt.

[travisahhs]

alright. Thats good to know. If you want to call this a stress test for the adaptor...

-I beat the first world of Doki Doki Panic with mama
-Beat the first 3 dungeons on Zelda no Densetsu FDS
-Beat the first world on Nazo no Murasamejou

All in one sitting, and I tested out several other fds and cart based games.

I guess i'm good to go. I didn't consider that the adaptor could have already been modified.

I don't know if this question has been answered yet, but I purchased my famicom and disk system in two different auctions. The disk system came with it's original power supply, and the famicom did not come with a power supply. Would it be possible to use the disk system adaptor on my famicom and just use batteries on my disk system?

[133MHz]

Unfortunately not. The voltage is compatible but the tips are slightly different in size and thus not interchangeable .
