View Full Version : NES A/C adapters.. now I'm REALLY confused.

Whenever I buy an older console.. I ALWAYS label the AC adapter that comes with it; and tests as working, 1st party one or not. I find it easier to find them with a quick label than comparing voltages, amperage and pin polatities later on.

Anyways.. I've had this NES top-loader for years in storage and as I said in the thread about cleaning circuit boards.. decided to "spruce it up" a bit today. I took it apart, cleaned the circuit board, polished the rusty RF gaurds with fine steel wool, and put it back together. Testing time.. and I pulled out the cables and adapter labled "NES 2". Mind you.. several years ago I knew nothing about how important it was to match voltages and amperages with the right console. I just assumed that if the adapter that shipped with the unit worked.. no problem; and this top loader had always worked fine the few times I had farted around with it.

So I looked at the A/C adapter today and noticed it didn't quite match. I think what the previous owner did was grab a 1st gen NES power adapter and had used it. On the adapter it says:

Model #: NES-002
outpt: 9V @ 1.3 Amps
For use with NES-001 only (which is the toaster)

On the bottom of my top loader it says:

Model #: NES-101
rating: 9V@ 850 mAmps

..needless to say I was concerned. These don't match.. so off I went tearing apart my room and storage looking for the right adapter. I didn't have one (of course) because this IS the one that came with my NES II (no box.. it was loose) so I started searching for one that matched.. but couldn't find an exact one.

Soes I go back to my NES II and flip it over and notice it also says: "Use with AC adapter no. NES-002 only". At this point I'm not thinking.. my brain's fried by now so off I go to eBay looking for a NES-002 adapter. I find one by model # and think "cool" this will match my NES II, so I double check the bottom of my top-loader once again to make sure.. then it dawns on me.. isn't this what I already have? Sure 'nuff.. I have 3 of these already.

My question is.. obviously there is a discrepancy between what this adapter puts out and what the unit needs. After reading a couple of weeks ago how too much amperage could fry something that doesn't need it.. I'm a little concerned. And also.. was there an A/C adapter included with top loaders that matched the voltage and amperage requirements of the model 2 completely? Or.. were there later model NES-002 adapters released that had a statement on them saying that they could be used on BOTH models (despite the amperage difference)? All of my NES-002s say they're for the NES-001 ONLY. I'm really confused now.

The "toaster" NES and the "top loader" NES use the same AC adapter, model NES-002. You have to remember most of the NES-002 AC adapters out there were manufactured long before the top loader. In fact I believe Nintendo didn't change anything when they shipped the top loaders, using the normal toaster power supply housing - which would explain why the warning for only using it with a toaster system is present.

Circuits "draw" current, they only take what they need - they are not "given" it like voltage. Both consoles require the same input voltage - 9V. Although 1.3A (1300mA) is being put out by the AC adapter, the top loader only draws what it needs, 850mA.

Also model "NES-101" is the model number of the top loader. "Output" is what the power supply is passing out, "rating" is what a device needs to operate.

the toaster NES has the same rating on the bottom of it both Toaster and top loaders take the same power supply and consume the same amount of power


I know David meant 1.3A not 1.3mA

you can look at it this way the units will consume up to 850mA
and the powersupply is capable of delivering 1.3A or 1300mA

some believe that the larger Powersupply was used in the case that a Expansion unit would be developed and be able to use the original power supply.
