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:

Power Supply
Connectors, for the corners
Mounting brackets and defusers, looks so much better this way
Individually assignable LEDs - purchased two of these
The controller
Power for the controller

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:
