Interface unit power dead...

[Hippokittie]

My interface unit's power cord got chewed through by my dog. Now I need to find a replacement one. Anyone know of one on like Amazon I can get? On a low budget...

[Black Tiger]

Are talking about the PC Engine IFU?

[Hippokittie]

Yes, the PC Engine cd2 interface unit haha.

[filler]

Has anyone suggested placing the PC-FX section of the forum underneath the PCE/TG16 section?

[Hippokittie]

If it helps at all I am in the United States

[Necromancer]

The PC-FX subforum is for the PC-FX system, the successor to the PCE.  Try to post future threads in the correct area.  Thread moved. 


There's this guy on ebay.  The description says it'll work with an IFU, but I've no personal experience with 'em and can't say if they're good or not.

There's also this one that's been recommended in previous threads.

You could also check with fellow member Keith Courage.  I know he's had some for sale before, either OEM or third party.

Didn't mean to post in the wrong area haha. Thank you. Would you happen to know what kind of chord to use for my pce interface briefcase?

If it's the same as the CoreGrafx/PC Engine (which I think it is) you could just use a Genesis Model 1/SegaCD power supply.  The 1602 is the model I'm talking about.

I always get a new power supply from retrogamesupply.com for Japanese systems.  They make new power supplies with the correct voltage and amps for the system and for correct use in North America.

I've used them for a Sega CDX I had, and for my PC Engine Duo.  They are not expensive either.

Here's the link for your Interface Unit:

In my opinion, better than the original japanese power supply.  Yes the japanese power supply does work in North America but it is not good for the system.

Just to be clear..... If you open a PAD-124 (Japanese PCE Duo Black) power supply and open up a US TurboDuo power supply they are exactly the same.
The extra 10v from our wall outlets will just make the stock power supplies run a little warmer. But anyone with a US Duo has been doing this since they came out in the US.

When it comes to replacement power supplies you want to find good voltage regulated supplies, with around the same volts output and at least the same or higher mA output.

7805 voltage regulators inside the machine are designed to handle between 7 to 35v I believe. So your just fighting a heat battle with the 7805 and there heatsinks. Keep the voltage max 12v regulated power supply minimum 9v with at least 1.5mA output.

Just find a connector or an adapter for a power supply that fits the unit properly with the correct polarity.


This one here has the correct polarity (center negative) and it is 5.5x2.5 the same as the original according to gamesx chart. It's 12v and 3A so it should handle everything fine. There may be better options out there, but this one would get the job done.

I havn't tested it myself but from all the specs this is more then enough and it wont run any hotter then the stock power supply. I know it says 9v on the stock power supply but they output more toward 16v and when plugged into the system they output more toward the rated values but still typically higher then the rated value. As they are not regulated power supplies.

My genesis power adapter only dose 500 Ma, dont I need closer to 1400Ma?

Yes, if you look at what SuperPlay posted here:

You can see the IFU takes:
CD-ROM2 Interface Unit   9V   1450mA   , center negative. 

The Genesis 1602 adapter outputs 9V 1.2A, which has always worked for me with the PC Engine and CoreGrafx (since they only need 650/800mA respectively accoridng to that list).  But may not be enough for the IFU.  I've never seen a variant of the 1602 that only puts out 500mA, you might be thinking of like the 2103 versions, but that type of jack doesn't even fit in a PCE.

Cheapest thing to do would be solder the wires back together on the one your dog chewed through.

Lol, that's a solid point.  He could probably even get away with just using a twist on connector, but he still needs to know which wire goes to the positive and negative parts of the plug.
