famicom step down and snes ac

[ramenlegend]

New here,
If i'm using a 100w step down converter, am I able to use an american snes or nes ac power supply? will it work and will it fry it?
Thanks

I don't think so.

To my knowledge, an American SNES PSU has the following specs:

10V DC 850mA   
(+)----(o----(-)   
Plug Size: Outer Diameter: 7.0mm | Inner Diameter: 1.0mm

That plug would not fit into a Famicom.

Easiest option is to use a PSU from a Master System 1/2 or a Mega Drive 1 PSU - won't have to worry about a stepdown either.

Yeah the American SNES one flat out won't plug in.

[Frank_fjs]

Does the American NES use the same PSU as an American SNES?

Not at all. The US NES takes 9V AC with a standard barrel plug, while the US SNES takes 10V DC with some sort of reverse barrel plug which is mechanically incompatible with everything else.

So what type of plug does the US NES take, 2.1mm x 5.5mm? Is it a negative tip like the Famicom?

Sometimes it's negative, sometimes it's positive

[Frank_fjs]

So it's AC?

[Lum]

Yes. AC is used by US/PAL NES, and PAL SNES.

US/Korea SNES just had a bizarre plug. They accept the DC rating from Famicom and Super Famicom.
So you can also buy a Japanese AC tap to run US Virtual Boy with normal plugs like Megadrive 1.

A lot of strangeness in this field... Sega actually switched American Game Gear to center positive (unlike most of the world)!

I find Sega to be pretty easy re PSU's, the Mega Drive 1 PSU is like the swiss army knife of PSU's, it runs almost anything! You can run the entire range of Sega consoles from any region with 2 different PSU's.

I use a model 1 Genesis PSU for damn near everything these days, I've even modded some of my other systems like my Twin Fami and PCE Duo-R with the proper jack so that I could save myself the trouble of having to hook up another PSU for those consoles.
