- Input: 110V-220V 50/60Hz; Output: 5V DC up to 20 Amps Max; The output voltage can be regulated by ±10%, from 4.5V to 5.5V, Works with device that draws less than 20A, such as DC5V1A~20A.
- The default input voltage is 220V, 110V/220V must be selected by switch before using to avoid damaging. Please replace the switch with the voltage appropriate for your project. High-quality raw materials, porous metal shell, good heat dissipation performance, small size, strong performance stability, only support indoor use.
- Make sure your device match the 5V voltage and wattage less than 100W. Please don’t run it overload .The max use should be no more than 80% of the full loads,otherwise, It‘s cause the power supply to overheat,the service life of the power supply will be greatly shortened.We recommend you to use this 5V20A 100W power supply to power devices less than 80W.
- Safety features: Automatic overload cut-off, over Voltage cut-off, automatic thermal cut-off, short circuit protection. Enough 100W output power and 5V stable output voltage will protect your electronic products from destruction.
- It is perfect for all 5V projects, such as WS2812B / WS2812B ECO / WS2811 / SK6812RGB / SK6812RGBW / WS2813 / SK9822 LED Strip / LED Pixel LED Matrix / LED String / LED fairy string / LED Matrix / CCTV Camera / Security System / Computer Project, etc.

Yes, still 5V. You may not find one in a wall-wart form, they're quite commonly like this:

And you need to use 14ga wire or thicker to run to the HAT (standard housing circuit wire will do). And if possible split the power and feed it to each board instead of daisy chaining it from board to board (otherwise you'll generate a lot more heat in the first boards).
I have a room that is 12 x 9, plus a small 3 x 3 area in the entrance to the room. I have run the following setup:
In my case I only had to add the power at the start of the entire string of LEDs. There are a number of libraries that you can use for controlling LEDs. I used FastLEDs (I believe that's right, I am not at my desktop machine so I;m not ABSOLUTELY positive.)
I also made a Windows app that is designed for running on multiple monitors. It shows videos (in multiple instances on each monitor) that are changed to the beat of the music and it can also affect the LED lights. It is written in C# and the entire source is available here: https://github.com/Blissgig/Lounge
Good luck.
I have decided to just build my own. I will be using a raspberry pi as the controller. Here are the parts list:
I will probably be building a web server to allow me to change the colors from my phone.
