I'm back with some more info. The question of how to power a Super Famicom pops up on here and other forums every few years, so hopefully we can come up with the definitive answer this time. And while this works for me, I have no idea if it will work for anyone else. My personal Super Famicom is the only one I've ever used.
No problem. Here are some pictures that clearly (I hope) show that this is an original first party NES AC adapter with a plug that fits the Super Famicom.Originally Posted by Satoshi_Matrix
These thumbnails link to larger versions for a closer look.
As you can see in the 3rd picture, the back of the SFC does, indeed, call for DC, but this adapter, outputting AC, works just fine (and has been working fine since I got the system in 1999). A mystery how it works, for sure, but it definitely does work without harming the system.
Maybe someone with some electronics knowledge can chime in with an explanation. For example, maybe there are diodes protecting the SFC from getting fried by the AC current, but it's still taking juice every time the current alternates to the correct pin, and capacitors are storing up enough to be able to deliver a steady stream of power? Obviously I don't have an actual understanding of these components, but it could be something along these lines.
The Super Famicom does use the same connector as the North American NES, but it definitely IS different from the connector on the North American SNES. That uses a weird connector with a very small center pin, unlike anything I've seen on any of my other consoles (of which I've had many, like all of us around here!)
And if you want to see this in action, I uploaded a video to YouTube showing the system actually running on this exact AC adapter.
Feel free to repost any of this the next time this question comes up, here or elsewhere, as it almost certainly will!
