I got a Sega Mega Drive 2 without a power supply and I've been told it can use a regular PS2 slim power supply, is this true?
Apparently the american Genesis 2 can with the US PS2 slim, I wonder if it's the same for the PAL (eu plug) versions.
It would save me money, most power supplies that I see are cheap chink fireworks in the making.
>And apparently the PS2 slim power supply is one of the most reliable for retro vidya out there, wtf

If you don't know what you are doing, don't try to color outside of the lines. Either learn what you are doing or stick to color by numbers.

It should work as long as it's 9V DC center negative. The symbol on a compatible power supply should look like pic related

I don't trust 30+ year old power plugs that weren't always owned by me, nor the chink cheap power supplies.
I haven't plugged it in, I asked first. Multiple places before 4chan (doing research).
Everything points to yes, including minor youtubers doing it on video without issues.
I figured I'd ask here too because 4chan has no filter and some anon could already be doing just that

What are you talking about?

Yeah learning what these symbols mean will help you a lot in the future. Well maybe not that much now that everything is USB-C, but you should anyway.
These type of barrel plugs are usually either:
Center Negative
Center Positive
You can see the open circle in the middle and the negative line is able to go inside of it, so thats "center negative"
>>
>>
>>12353719
The Mega drive 2 (and genesis 2) are center positive, unlike the first model.
The ps2 slim power supply is also center positive but 8.5V.
Apparently that's fine because the genesis has an internal part that further reduces the voltage to something like 5v or 1.4v, whatever it is that it works with internally, hence it being slightly under not being a problem.
>I should have titled the thread question as, "Has anyone here ever powered a Mega Drive 2/ Genesis 2 with a PS2 slim power supply?"
What I really want is the notes from someone who is already just doing this

From what I've seen looking through sega MD2 power supply replacements to buy, the original power supply was not so regulated, it could pull 9 to 14v from the wall.
But yes, everything was properly labeled as center positve or negative.
>Also interestingly, the best replacement available right now is made by Triad magnetics, an industrial/medical manufacturer of power supplies. Their power supply even comes with different country plugs, which is interesting.
Too bad it's 25€ + at least 10€ for shipping. That's more than what I paid for the console. If I could save that, I'd be happy

I've used a psp power supply with this and 32X, its only 7.5 V but the connector and wire are better quality than the original and I feel that there is less screen interference when using long av cables to the TV.
>>12353769
My Megadrive has lower image quality and might crash below about 11 V when using a Mega SD.

You should still try to remain within spec, higher voltages mean the regulator generates more heat and the heatsinks in most electronics are usually as small as possible to save on cost and space.
Similarly, you shouldn't be using too low of a voltage either. While your device might work on 7 volts, and your power supply says it provides 7 volts, most wall warts and other simple power supplies tend to have their voltage fluctuate quite a bit so it could actually be providing 6 volts or 8.5 volts instead. Too low a voltage and you might get weird behavior like the console freezing seemingly randomly.

I see... Maybe that's why the PS2 slim power supply is considered a great replacement, it suposedly does not fluctuate very much and is near 9V
Also, from what I've read and seen of tests, the original Genesesis/mega drive 2 power supply, althought it says it's 9V, it could go up to 14v

Just make sure it's the right voltage

Thanks anon!

I had that exact link bookmarked. I just wonder, if the ps2 slim power supply (which I have) works perfectly, why not save money?
>>12356171
I see... From what I've read, the OEM sega power supply only got to 12v either rarely or if the console had no games, something like that.
Still, for my purposes, if the 7805 reduces voltage either way, 8.5V should be fine, right?
>>
>>
You can use the PS2 power supply with Genesis 2, I have one and did it before. Both Genesis consoles use 7805 regulators inside so you could power them with 5V or 15V power supplies too, as long as you adhere to the plug polarity and the physical size of the plug.

Center negative is Genesis 1 and Sega CD (and some old famiclones).
Genesis 2 was center positive, aka normal.

You should always use the same Voltage + Amperage requested by a system.
If you use a lower amount, you are putting more strain on the components inside the system and they may be getting much hotter than designed for.
And obviously, if you use higher amount it will trip the fuse/fry something.
0.5v might not be that bad though
