UK Console power supply's on a PCE Duo

[PCEngineTrev]

Hey guys,

Does anyone know what UK console PSU's are compatible without issues on the black PCE Duo?

I grabbed a Duo for a good price recently but it didnt come with a PSU, was hoping to save cash buying one.

I know the Mega Drive PSU can work with the original white PCE, is that the case with any other models? Thanks!

Search gor "Replacement for 10V 1A AC Power Adaptor 6.3mm x 3.0mm for PC Engine Turbo Duo" works a treat. I ise it (amongst others" with a eu adapter.

Best to get 10v with minimal 1000mah, why not have a look at maplins or ebay

I'm using an universal switchting mode psu like this one from Goobay for my Turbo Duo:



The specs say 60 W, so there's plenty of angry pixie flow available even at 10 V DC. Also pretty handy when doing electronics projects or just powering other devices that are more hungry than a Duo.

From the nuggets of info Ive found on the interwebs, it looks like nothing for UK consoles works on a Duo. Managed to pick up a good power supply from these guys though:

I'm concerned if a 9V, 1A (9V * 1A = 9W) supply would still be able to deliver enough power for a Duo, which is expecting 10V, 1A (10V * 1A = 10W). I'd rather go for something that complies with the original's specs.

I’m just always wondering why people think scrambling for other 30 year old power supplies that also sucked is a way to power anything.

Buy a new switching power supply. It won’t match the original but it will be smaller and use massively less juice, especially when the unit is off. Then, when you go to use you Genesis or whatever it will still have its power supply.

From my experience 9W is enough for a Duo. Probably about 6 or 7 W is where it will start to see trouble during peak current demand (CD seeking). However, yeah, there’s no reason to restrict it.

Since I have trouble to recover my adjustable power supply brick that I had shown above, I'm thinking about getting a small dedicated supply for my Turbo Duo.

10 V supplys are rather scarce. Will 9 V / 1.3 A (12 W) be fine? Those are more common. I can replace the tip with one that fits my Duo.

yes, 9v is fine.  its easier to find a power supply with at 5.5x2.1 tip.  also probably easier to find one with 1.5a or 2.0a.  these make it easy to adapt to work on a duo.

I didn't know about these tip adaptors, thanks for mentioning these and providing a link.

Switching mode power supplies can cause visual interference on some old consoles though as they were made to use linear supplies.
I have a switching mode supply for my SFC original model that works fine but displays interference on a 1chip console.
The same power supply causes interference on my Core Grafx.

[ClodBuster]

I had both a linear lab power supply as well as the switching power supply mentioned earlier on my Duo and couldn't spot any difference.

Mind you that both the lab supply as well as the switching supply were oversized for the job.

I wouldn't be surprised if some cheaply made miniature supplies have the potential to introduce visible or hearable noise, regardless if switched or linear, each in their own way.

I wish there would be more namebrand manufacturers for the small universal switching supplies. When searching on the web, often times you'll just find the usual bunch of strikingly similar looking models just with different off-brand names attached. I'd even pay some premium if I am garantueed to get my hands on a wallwart switcher that neither does introduce noticeable signal noise into the attached device, neither annoy you with humming or chirping sounds emitted from the supply itself.

And no, I don't mean this in an Audiophile esoteric snakeoil way, f*ck those guys.

All I want is a product that is guaranteed not to suck.

For shits and giggles, I measured the current draw of the Turbo Duo when playing games, using my lab power supply set at 10 V DC.

For Hucards, Blazing Lazers draws around 700 mA constant after a couple minutes of playtime.

For CDs, loading Gate of Thunder draws slightly more than 1 A at peak. If I set the power supply for a strict maximum current of 1 A, the Turbo Duo will refuse to finish the loading process, as the supply is switching to constant current mode.

For future reference, could you do that with an EverDrive?

[ClodBuster]

I don't own an Everdrive, but I got a poor man's PCE flash cart I can dig out and test. I can also use my DMM and see if it has a min/max function for detecting peaks.
However, this is about total current draw of the console, not the current draw between cart bus and the cart itself.

Also, there had already been measurements made by db electronics on the current draw of everdrives, so there's no need for me to repeat that.
