A bigger and better PSU for larger DIY modular and/or synthesizer projects. This PSU also includes +5V.

What is it?

This is an improved power supply over the earier PSU1 that had smaller capacitors and only +-12V. This power supply have 4700uF capacitors to reduce the risk of ripple, and also have +5V along with the the +-12V. When using this power supply for a larger amount of modules you will need to add heat sinks, which is easily done as the power regulators are mounted on the sides of the PCB.

Why did you make it?

I built this as my second Power supply when I got problem with ripple in my smaller power supply. Also this power supply is made to use with the special eurorack power cables and power rails to distribute power, and also has +5V on board. All these were features that I found was good to have after doing building a modular for a while without them.

What makes it special?

This is simply a vanilla modular power supply. Nothing really makes it special, except maybe the price which I try to keep as low as possible for more people to be able to get into Modular. It is also very simple to build this power supply yourself on a veroboard or protoboard (maybe the P-0+o). Just follow the schematics.

You can find the schematics here

There is also a really slow video showing the whole build process from start to finish that can help you a lot in building this: Click here to watch the video

For those of you who have trouble finding tha AC-AC wall wart adapters:

Here is a Jameco 12VAC adapter on Amazon, sent from the US: https://amzn.to/2Z2yaIg

Here is a 12V AC-AC Adapter from ebay.com, sent from Germany: https://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&toolid=11800&pub=5575103922&campid=5338181421&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F264529555139

I found this one here on Tindie that should work fine for this (and other) power supplies, shipped from France: https://www.tindie.com/products/dhaillant/acac-adapter/

And here is one shipping from the UK that should work aswell: https://www.poweradaptorsuk.co.uk/2500ma_12v_AC_AC_Power_Adaptor_p/ta250012ac.htm?CartID=1

And here is one from Thomann who ships all over Europe, it is only 650mA though so maybe a bit on the small side... https://www.thomann.de/fr/the_tmix_mix_1202fx_psu.htm

Paris | May 3, 2023

absolutely perfect

I was building a station for calibrating my builds I did not want to over tax the power supplies for my euro-racks and needed a small but robust PS, the price , speed in shipping, and simplicity made this unit perfect, 1/2 hr build and I was able to mod the build to my specific needs , too cool, thank you very much, I will be in touch for more kits! I did give you 10 stars across the board

Ken | Jan. 6, 2023

Great!

Quick shipping, easy build and very responsive. I would and probably will order again from this store.

Anders | Feb. 18, 2021

Great price and nice communication

Christian makes affordable modules and has an amazing YouTube channel where he takes great care explsning and being helpful.

Andreas | Feb. 16, 2021

Great little power supply!

This is a perfect and very reasonably priced power supply to test out my DIY modules before putting them in my rack. The build guide is clear and online video takes you through the steps in an orderly manner. Highly recommended!

Marcus | Nov. 28, 2020

Great to start

I'm just starting on eurorack and DIY and the psu was my first DIY projects I bought. I was a bit worried to start but everything went really well. I've done following his video that he goes through all the process making it easier to follow.
So, overall it's a cheap way to start on eurorack and to start DIY!
Also arrived super fast!

Edward | Nov. 14, 2020

must-have for Eurorack diy

I am at the beginning of my Eurorack. My plan is to build all modules myself - I find your PSU very useful. I also discovered your YouTube channel. I am inspired by the way you build your modules in the videos, I think I can learn a lot from it. Thanks a lot!

Phillip | Oct. 23, 2020

Great product. Easy build with a nice video tutorial.

The most economical supply out there.
Easy to build. Nice video tutorial. Prompt shipping and great communication. Do yourself a favour.

Bruce | Oct. 17, 2020

Easy Power

This is a great Power unit, even for a beginner. Easy To Assemble, and the AC-AC adapter was not that hard to find. Just the right fit in just about any case. :)

Jonathan | Oct. 4, 2020

Good sturdy PSU with plenty of power

It features plenty of power options, creating my own power source for it wasn't so bad either. Nice build. Enjoying the options it provides to my builds. Thanks.

David | Sept. 13, 2020

Excellent simple 12V and 5V power supply

If you need a really simple and clean power supply then look no further.

Designed for Eurorack projects but can be used for many other things as well - as i have done!

I got two - one for a fixed system and another to play on my bench.

Great stuff!

Jared | July 23, 2020

Extremely affordable

Easy as heck to build and good quality components and great value!!!!! I want to purchase a few more but they are out of stock! :(!!!
Only thing is I want to know the amperage output so I know how much draw my little system can deal with

Bert | July 20, 2020

Perfect for a diy eurorack!

Great PSU for a simple diy eurorack! Great seller with great youtube channel! Recommended! Thanks for the swift shipping!

Kalle | July 18, 2020

First step made easier

When you're about to dive into the sea of modular synths, the first obstacle is affortable power source. This is a perfect price range for your first modular. Documentation could be more specific about the requirements of the AC/AC adapter this needs.

Excellent kit to start off a rack

Been a fan of the MIAW YouTube series for a while and its been a fundamental learning tool for me as I've been learning about DIY modular - not to mention entertaining. I've been building along with the series, making do with a couple of 9v batteries for power, but now I want to build a rack and this module is the perfect kit to begin! Super simple (only needed the schematic to check stuff) it practically built itself and everything tested just fine. So now I have a nice clean source of power - time to build the rack and upgrade the modules I've done. No doubt I'll be back here to get the PSU expansion boards before long.
PS. Delivery was a couple of weeks which, considering the current state of things, was not bad at all - excellent communication from the seller!

Yann | June 28, 2020

Thanks

I started watching your youtube channel and I started the MIAW adventure. thank you for everything you do.

Ricard | June 25, 2020

Great!

Bought this as my first entry to eurorack and will start to buil it as soon as possible, the seller was responsive when i asked him a couple questions and answered fast. Overall good first powersource and ultra cheap and small. thanks!

Power Supply 2 - Great project for learning about power

This little power supply kit is a great buy, from a Tindie seller who has been quietly building some fantastic things since the shops opening. This was my first purchase from this seller, and one of the first purchases from Tindie, and I'm extremely glad I bought it.

The only slight complaint I have is that the PSU documentation doesn't list the current output. I would be curious to know.

Marcos | May 24, 2020

Very easy to assemble

This was my first circuit that I soldered. I am glad that Kristian made a video to explain each step. Keep up the good work

Martin | May 20, 2020

a nice little kit

A very straight forward build, well demonstrated. the circuit is basic, but works well. It might have been better if a make / model of wall wart was recommended, but it was reasonably easy to find one that suits, even though nearly all search engines insist on prioritizing results for dc output types.

David | May 12, 2020

perfect

Just started the MIAW series, this PSU is just perfect. Easy to build, either for a beginner. My order arrives in excellent condition, very well packaged.

I'll buy again from this store!

Antanas | May 8, 2020

Perfecto

Seller was really helpful and friendly. Shipping took time but taking the situation into consideration its was expected and not a problem. Will buy again in the future. Definitely recommend this seller :)

Craig | March 9, 2020

Great value power supply

I found it easy to build for someone who doesn't have a lot of soldering experience. Packaged well, and delivered quickly. I look forward to following along with the modular in a week youtube series as I start down this modular rabbit hole.
