Correct PSU For Nintendo systems?

I have a Super Famicom, NTSC SNES and NTSC NES (Toaster), i am currently using this PSU which is a Official UK PAL SNES (could be NES) on all 3 consoles.....



But it recently come to my attention that the Super Famicom should use a DC PSU not AC, if this is so then why has my Super Famicom been fine for over a year now??

 

Would this be suitable for a Super Famicom........

it needs to have negative inside. You can buy this one and cut the coord, and resolder it the other way round

 

NTSC SNES and NES should not even have the same connector lead so I am wondering how you can use the same adapter on both, not to mention this is an AC adapter and as far as I know NTSC snes does not work with AC.

Edit: Does the adapter has two different leads? Like a 2 in 1 ?

 

I'm under this impression too. The NTSC NES takes 9V AC, however DC can be used too. The Super Famicom, takes 10V DC, as does the NTSC SNES. The US and JP systems have a completely different power jack. Nintendo of America specifically changed the power jack on the SNES to be non-standard so you wouldn't use a NES power adapter on it. Presumably because doing so would damage the SNES with the AC current.

So again. NTSC NES takes 9V AC (will tolerate DC). Around 850ma to 1 amp I guess.
Super Famicom 10V DC. Do not use AC. 850ma.
US SNES 10V DC. Do not use AC. Custom Power Jack should prevent that anyway. 850ma.

Edit: Forgot to mention with DC you need to pay attention to tip polarity. SNES US says tip negative I believe.

 

They say you can use the Genesis Model 1 AC adapter for Japanese Nintendo systems.
American systems are a different story. The SNES has its own plug, despite it using the same power as the Genesis Model 2. NES can run on anything, its own plug or a Genesis 1.

Just don't leave anything plugged in for a prolonged period of time.

 

The Genesis 2 power adapter (also the 32X adapter I believe) is center positive so it would not be what you want for the SNES even if they used the same type of jack. You could physically plug the Genesis 2 adapter into a Super Famicom but that would be bad as the polarity is reversed I think.

Really it's important to use the original power supply or if you can't to use another with the exact same specifications, AC/DC, Polarity, Voltage, and Amperage.

 

Yeah sorry my mistake, i do not use the NTSC SNES with this power adapter just NTSC NES and Super Famicom, as you guys rightly said the NTSC SNES has a larger tip than the super famicom.

Question is then where can i find a replacement adapter for the Super Famicom for UK use i only really see 9V and 1A adapters, ideally id want a 10V, 1.2A adapter wouldnt i??

So are the NTSC NES, SNES and Super Famicom all negative center pin??

 

Model 1 genesis/mega drive power supply works fine as it has same specs tried it myself and has no issues.

 

I believe the UK MegaDrive is AC not DC

 

^^

^^ letter for letter copy where possible?! (from my mains transformer)

 

Hmmm all the UK MegaDrive 1 Adapters ive seen dont mention AC or DC, just say 10v---1.2A

 

the '=' sign IS the DC mark.
~ is AC and...
= looking sign is DC.
[edit]

^^ exactly!

 

So the symbol with the line and the broken lines under it means 'DC' then??....



i never knew that

 

aye, it is!
keep those two glyphs in mind and you'll not go wrong!

Funny thing is, some SFC consoles can run on AC with little to no problems. My colleague tells me that it only uses half of the power because its regulator filters away half of the current in the Alternating Current (AC) and so it can't run some power hungry games...
However, in a little test I made, some SFC consoles will flicker terribly and die with an AC adapter. I think the early models do it.

 

What the actual size of the NTSC SNES socket that plugs into the SNES?

 

I'm not sure, but I imagine it could be swapped out for the same type of power jack connector used in the Super Famicom and Sega Genesis.

 

It is a weird size. I searched for replacements often but never found anything.
When they break here is what I do.
Look down the thread for picture details.

It not that is broken, im after getting an extender adapter, but need to know the size, i know its 7mm but im not sure of the other size, im guessing its 2.1 or 2.5mm??

EDIT, think its 7mm x 5mm
