Definitive? PSU answers

Jeff, if you mean the kinda thing you got on the SNES over there, we don't have those over here.

OK, here goes.....

Mega Drive (Genesis) rated 10V 1.2A DC(doesn't actually state AC or DC, but I got a 13.8V DC reading and 30V AC so its DC).

NES/SNES 9V 1.3A AC

Jaguar 9V 1.2A DC

Note none of mine had AC or DC written on them, I found that myself - although the later NES units did state AC.

Now, if the Neo takes 10V 1A, then a 1.2A or 1.3A supply will be safe - its generating enough current for the unit. So we're ok from that point.

All these adaptors have the positive connection on the outside, so again all are OK.

Now, we have to get the AC/DC rating correct. I don't have the original PSU, but the back of my Neo Geo AES says DC IN (why has noone seen that before?). So, we should all be using DC units. In other words, those of you trying Nintendo units, STOP! It may work, but if you want to keep your Neo I'd suggest either getting a proper PSU, or a fixed voltage REGULATED one, or use a Sega unit.

All master system, megadrive/genesis 1, and game gear units should be ok - mega cd/sega cd uses a slightly different unit which still should be ok as long as it gives 1A or more (and is DC).

The Jaguar PSU should still work, despite being only 9V - actually I goto a reading of 12V on mine! But if you have to go for the alternative system option, I'd recommend the Sega units.

Hope this helps <IMG SRC="smilies/wink.gif" border="0">

actually...a game gear one may have the right output...but it doesnt have the same plug. its the same as the gen 2 and i think 3 plug

the GG one only outputs 800 mA, that's not enough.

my famicom ac adaptor (jpn nes for all you that might not know) is rated as DC10V 850mA and it works just fine on my neo

and my genesis adaptor model:MK-1602 is rated as 9V DC 1.2A

not to mention that every single sega cd and genesis 1 ac adaptor i've come across are identical. same model and everything.

Ok, well over here in the UK, Game Gear has the same connector as the Mega Drive. I'dve thought it should there too, being the same worldwide!

OK, the Mega Drive here has a 10V PSU, but the Mega CD manual has a warning against using a Mega Drive PSU - but the difference is just the 9V 10V thing, which is fine.

Thanks for the Famicom info. However, UK and US NESses should be avoided if they output AC. The Jap Super Famicom (SNES) should in theory be AC still.

Any doubts, go to Maplin, Radio Shack, MCM..... those large companies do fixed voltage/current regulated PSUs.

I take it we're in agreement on the Jags then? <IMG SRC="smilies/biggrin.gif" border="0">

no ones got a jag to confirm it anyway <IMG SRC="smilies/loco.gif" border="0">

my genesis 1 PSU works on my jaguar, so the jag one would work too for sure.

I have a generic 10v DC 1.1a that will not work. My Genesis model 1 AC will not work either. Oddly enough the only adaptor I have gotten to work(I haven't tested with any games yet as I haven't acquired any) is a NES adaptor which is a 9v 1.3a. Anyone think there might be something wrong with my system?

Mike, the AC one shouldn't work.

Generic usually means multi-voltage unregulated - as I said stay away from them. Put it to 10V, you could be pumping 18V continuous, with over 20V peak - current could be too high/low too (not regulated).

Try a pair of headphones in the front when you turn it on.

My atari jaguar adaptor works fine on the neo geo,you can buy them adaptors for around £5 or if you want buy the system brand new,
you can pick up a brand new atari jaguar for around £15 so if you cant get the adaptor on its own buy the whole machine take the adaptor out then throw the system in the bin.
