Whats better to use. The Sega Genesis power cord or the PS ONe cord. I have the Genesis one, but i heard that the PSOne power brick works too. I heard that the Genesis one runs hot.
Thanks,
Mason

Don't use either.
Go buy a new adapter from Radio shack and match up the amps/volts/connector.
All Genesis bricks run hot IMO, screw that.

So does anybody know with one from radio shack I shod get?? What size of connected?
Thanks

Search says you want the 9V 1.5A adapter (part no. 273-356 (http://www.radioshack.com/product/index.jsp?productId=3807943)) with a 'Q' plug (part no. 273-347 (http://www.radioshack.com/product/index.jsp?productId=3780270)). :wink:

Thanks for that info! I have a Duo-RX I just got recently from a guy with a bunch of other stuff and the adapter is not stock so I've been hesitant to use it too much until I could figure this out.
Do you know if there's leeway in the voltage though? I know the Genesis 1 says 9V but has a tolerance of up to around 12V since the 7805 regulators in the console can work up to 12V. I don't know much about the Duo yet so I've no clue what's best for it.
-
So the radio shack potion is the best one then...
-
Yes. Get the one from Radio Shack. It's PERFECT.
-
Why does it seem that so many people need power bricks for these systems?? Its thine they all dissapered.

Died of old age? Cats chewed up their cords? Destroyed when two were tied together and used as a bolo?

i was shipped an NEC AC power supply with model number PAD-129
input: AC100V 50-60Hz 20VA
Output: DC9V 1000 mA
IS this the right one, or should I still get a radio shack one.
Thanks,
Mason

I just took my system to radio shack and said " I need a power cord for this". To which the person responded...what the hell is that?...lol.

I did that only I walked in with my duo-r and when they started with their expertise I said gtfo, I got this.
Dude told me all Japanese consoles require a step-up for US.
and then told me that you need step down for UK in the US, since I asked about a step up for an MSX while I was there.
Yeah, I step down to 220v, totally.
herp^derp.

You too? It happens to me all the time, looking for computer parts. I once had an obviously new cleark determined to "help" me picking out memory. I told him I need a stick of 512K DDR 66MHZ. He spent about 20 minutes looking for one.
The local computer stores know me by sight after a few of those. The long-term clerks just tell the newbies to leave me alone, I know more about it then they do. Especially after I told one of their customers to change wireless phones when his WiFi kept dropping. They never knew that wireless phones and 802.11G use the same 2GHz range. Sad.

Yeah. the microcenter minions kind of ignore me now. Its a good feeling.
Then, I peel their stupid commission name stickers off my stuff that they didn't pick out.
Fight the power.

If what Necromancer says here is right, the adapter you have now is deficient by half an amp to run the Duo. It may run fine without it, but if it is underpowered over a period of time it could cause damage.
I haven't been able to find any information so far about what the specs for the official adapter are, and if there is any tolerance in voltage. I just don't want to go out and buy yet another adapter just for the Duo if an existing one that I have will suffice.

yup this is the right one for the Duo-RX and it will work for the Duo-R as well.
-
Well on the bottom of the system it has the PAD-129 number on it. I figure this must be the AC adapter that came with the system.
-
PAD-130 will also work for duo-r(x) as well
-
Okay, as I suspected, even if you don't have the correct adapter, you don't have to go out and drop $40 on the Radio Shack one.
After a little digging I found this thread: http://www.pcenginefx.com/forums/index.php?topic=2960.msg37827#msg37827
You guys are reading WAAAAAYYY too far into it. Everything inside these systems runs at 5v. They use your average run of the mill, dime a dozen LM7805 type linear power regulator. This is connected to a heatsink. You need at least 7.~v input to produce a stable 5v output. Most power adapters are at least 10v to compensate for power fluctuations (your 110v a/c wall socket).
You can feed up to 30v into most 7805 varients. What happens? The extra voltage is turned into heat. If the heatsink isnt big enough, the LM7805 will shut down after a while (they are internally protected). Worst case is you'll fry the 7805 and/or the system fuse. 9v, 10v, 11v, 15v, doesnt matter. The important thing is the adapter provides enough amperage, and polarity is correct.
So essentially, as long as the polarity is right and plug fits, anything in the 9V-12V range that's putting out a minimum of 1000mA (1Amp) or more will power the system no problem. Excess voltage is turned into extra heat, and excess amperage is just not used by the system.
Someone does mention later in that thread that Duo-R/RX may not have internal fuses, but I can't confirm it anywhere else.

I bought a multivoltage 1.5A from Radioshack and while it fit the socket and powered my IFU-30 (1450ma) on it couldn't spin the disc fast enough to load. I had to sent it back. I've heard these multi PSUs can't provide full ampage at the higher voltages.
I'm now waiting on a generic 9V 1.5A psu and I'm planning to just cut the jack off it and re-attach the one from my 110 psu.
Here's hoping it works this time.
