Need info on a UK/Europe PSU for RetroPie setup

[AndersHP]

Hi y'all.

I'm in the middle of planning my first arcade bartop, and I am going for the RetroPie setup, but am struggling to find a proper way to power Things up.
I have the following requirements for my PSU setup (please advise if something is impossible! Thanks.)

* must be as simple as possible - meaning I would rather have one PSU running everyting at once, than a 5-6 slot power strip with AC-DC converters in each.
* must provide 5V / +4A (for Raspberry Pi, heard 2A could be too weak) simultaneously with 12V / ?? A for illuminated buttons and LED for the marquee as well as a Little sound amp for the speakers. I guess if the Amps are high enough it will be possible to connect all these Things into the same 12V output, yes?
* have to run silent, meaning no PC power supplies. This should be possible.

Would this do the trick?

I'm not sure if the 16A is too much? Will it fry the Raspberry?
Also, is there a problem connecting the amp to the same PSU as everything else? Could this result in sound interferences?

Anyone?

This must be easy questions to answer for anyone who's made their own arcade?

You could probably use a power supply that is used in original arcade cabinets. They supply both 5 and 12 volts and have no fan.


Example:

Just noticed you linked to one almost identical to the one I linked to. It should work fine. 16 amps at 5 volts is more than enough, just make sure you don't need over 4 amps on the 12 volt side.
Also, the 16 amps 5 volt should be ok on the Pi, it will only draws what it needs. The power supply can put out 16 amps, Pi will be ok. You can adjust the 5 volt power to get exactly 5 volts, or maybe a fraction over. I heard the Pi 3 likes around 5.15 volts, but not 100% sure about that.

Thanks for the reply, man!
Cool, I'll get one of those then. 4A for lights should be okay, shouldn't it?

Would it be better to separate the stereo amp from the rest, by connecting it directly to 230V? I'm thinking interference and whatnot...

I would think 4 amps would be enough for lights, especially if they are all LED lights.
You can try the stereo amp, but if it pushes the power supply too much, the power supply will most likely turn off, you would have to reset it powering it down then back up.
Might be better to go safe and power the amp from 230 V, if thats not going to be a problem.

Hello again

I've changed my setup a bit, separating the 5V from the 12V and also separating the audio, to run from 230V instead.
So what I need is a cheap, stable 12V PSU for illuminating my buttons and probably the marquee also.

Any suggestions (NOT PC psu since I don't want fans running) would be highly appreciated!

Why is the audio needing 230v?

Was going to suggest one of these https://www.amazon.co.uk/DROK-Output-Universal-Adaptor-Display/dp/B00HY3AA3S/

I used one in my Pi build here http://forum.arcadecontrols.com/index.php/topic,151195.0.html

I love your daughters mini arcade! Just awesome work! 
I am separating the audio to avoid interference. Also, I am thinking of using a Logitech 2.1 sound system to have both good sound, as well as a built-in volume regulator and audio jack for headphones. I cannot find a 12V amp that does all these things at the same time. Plus there's the risk of getting interference on the sound.

But hey, that little PSU you linked to is not that expensive, maybe I'll pick it up anyways.
