Famicom + Disk System Power supply

beardcore84

Hi all,



I recently picked up a Fa micom and a Famicom disc system. I understand you can run these with a US Genesis Model 1 Ac Adapter. The bundle came with one, and I knew I had another one at home (one for the famicom, one for the disk system).



My question is, the readouts are different on my adapters. The one that came with the famicom reads:



Input: 120V AC 60 Hz 20 W

Output: 10 V DC 1.2 A





The model one adapter I have reads:



Input: 120V 60Hz 35W

Output: 9V DC 1.2 A



I don't want to risk frying the systems. Will the adapter I have work to power the disk system, or do I need to find one with the exact specifications as the one that came with the bundle?



Thanks in advance!

Model one sega genesis psu will work just fine,also if you want to run both the disk system and famicom off the same psu than a splitter will work great as well.

Thank you! Just to clarify, even though the Wattage and Output Volts are different, both of them will work? (To be clear they are both model one Genesis AC Adapters).



Thanks!

The voltage will be brought down to 5v internally, so the difference between 9 and 10 volts in won't matter. You do need to make sure that you are providing enough amps to properly power the device. In this case the amperage is the same, so you're good.

Thanks Duke!

Same polarity (center negative), same tip (5.5x2.1mm), and enough amps (1.2) = perfect.



The Genesis MK-1602 is useful for a lot of stuff! Because it is DC center negative (not common outside Japan in that era and not common anywhere today) and it has more amps than most it can be a real workhorse for your retro gaming collection, particularly if you import and don't want to subject your import consoles to 20% higher voltage they are likely to receive if you use their original PSUs in North America. Output voltage scales linearly with input voltage for the old linear-type power supplies, as opposed to today's compact, lightweight, switching PSUs that take 100, 110/120, and 240v. Family Computer, Famicom Disk System, AV Famicom, Super Famicom, NES, toploader NES, Master System, Mark III, Master System II, Japanese Virtual Boy Adapter Tap, PC Engine, Core Grafx, TurboGrafx-16, Core Grafx II, Sega CD, Neo Geo AES (the later 9v consoles; not the early 5v ones!), Atari Jaguar...



...and the Genesis (of course).



Using any of the original plugs from these other consoles to power any other isn't always a great idea. The NES outputs AC and can fry any of the others though it works with DC just fine. The TurboGrafx-16 outputs 10.5v and will generate more heat. They don't usually have as many amps either. Plus, unlike many of those, some of which are uncommon and expensive, you can still get these new from a certain eBay seller. You're a lot more likely to already have extras versus a Neo Geo AES or TurboGrafx-16 PSU.



That said, I use my TurboGrafx-16 PSU as another workhorse since I use the Turbo-CD and the dock requires 5.5x2.5mm (no longer fits the console's original plug). You're actually expected to repurpose it for the undocked CD drive to turn it into a semi-portable CD player, but what a waste, right?!   The 9v Neo Geo AES actually included either 10v or 11v adapters (PRO-POW3 and NEO-POW3) so it tolerated both, making the TG-16's 10.5v PERFECT for it. At 730mA it doesn't have the amps that the Sega MK-1602 has but the 11v Neo Geo PSU was only 700mA anyway (a little extra amps is not a bad thing). Because it's already in place, I frequently take advantage of it for other consoles. Most recently I swaped it to the SFC, Genesis, AES, and others when testing the OSSC and HD Retrovision cables.
