Hello!
I got a famicom today.
It came with this power supply.
You cannot see attachments on this board.
Will it work if I plug it in? I'm in the US.
Thanks.

yes :)
I've been using the original Famicom AC Adapter with my Famicom ever since I got it and never had a problem with it. I do however unplug it when I'm done playing. By doing this the PSU won't overheat, and you save some pennies on your electrical bill :) These AC Adapters already have tons of use on them so they will eventually die just like everything, don't let that be your deciding factor.
If you're using a Famicom I recommend this:

It will work until it dies. Pushing 120v through it for an extended amount of time will eventually kill it. Replacement adapters are around $9 to $10 on eBay.
I would not recommend using it.
That's only a half truth. It's a linear power supply. All that will happen is the primary coil will energize the secondary to 11-12 volts instead of 10 under load. It's actually not as bad as everyone claims. Even the amperage scares aren't that bad.

Yes and 7805 voltage regulator have operation range from 7.4V up to 24V. So it is totally save to use this on 12V enstead of 9V. It have radiator after all. :)
This is 9 V though, not 12 V. But yeah I imagine that 9 V would cause less heat than what 10 V would which the official AC-adapter use. I think the question was whether an input voltage of 100 V instead of whatever Americans has in their walls is fine or not. American AC-adapters often seems to use 110 or 115 V input, so I'm not sure what comes out of their walls (110? 115? 120?).
Many people's answer to the topic question is "it's bad" or "it's not as bad as many people claims", but what I'm interested to know if it's bad at all or not? And if it's only the AC-adapter itself that's affected or not? Otherwise it will just be an endless and useless discussion of "it's probably bad but probably not that bad" and so on.

While yes you are correct, the difference of 2-3 volts being bled off in the regulator might see an increase of 3°-5° celsius, which the RF cage is more than capable of dissipating.
There is no problem using 100V transformer in 100-120V socket,just like in Europe we have 220-250V range power outlets, no problem here.
But that's the power supplies that are tolerant of the range 220-240 V so that they work all over Europe. It's not the wall that are outputting a voltage range. Sweden has 230 V ±10% in the walls but used to have 220 V (according to Wikipedia).
As sanoe one above mentioned it is not big deal that the electricity is not that stable. Transformer rated to 100V input and 10V output in this situation will be outputing 11V/12V from 110V/120V input, and as I mentioned in one of mine previous comments about 7805 this is not big deal and there is no reason for panic.
We know that. That's not the problem.
