Here's some of what I used for this project if it helps anyone

Happy to help!
This is the one I used for my 288 LED project, and it is holding up very well: https://www.amazon.com/dp/B06XK2DDW4
These types of power supplies are used for 3d printers and the like. It's totally safe if you wire it up without it plugged it. I know mains voltage scares people, but it's really very easy.

That should work for all 4 boards.
I built mine using the following hardware:
- LED Light Strip (Black PCB 5m 30 ip65)
- WeMos D1 MIni (Flashed Tasmota on it)
- 5v 20A PSU
- Radar Motion Sensor
- Home Assistant
- MQTT Broker
​
With my setup, I keep my motion sensor and PSU on top of a microwave in a cabinet, such that it has clear view of a person entering kitchen. When someone enters our kitchen after sunset, LEDs turn on (and stay on while there's motion). When there's no motion, they turn off after X number of seconds.

I hope you find this useful and it gives you some ideas
Would this not work?

You are very welcome. Might I ask, what 'thing are you making? Why start your arduino career with this project?
.
Since you gave such nice feedback, I offer you are few more pieces of info.
My estimate of the current required is between 11.5A (5760.020) and 34.6A (5760.060)
These are based on the 20ma per LED or 60ma per LED on the link "Estimating Power Requirements".
The power required from the supply is between 511.5 = 57.5W and 534.6 = 173W
.
Here is an example supply midway between the extremes (this is an example, not a recommendation)

I didn't check the links to see if they explained about wires, here's a link to wire gauges vs resistance
https://www.engineeringtoolbox.com/wire-gauges-d_419.html
.
What wire gauge and length is important, because of voltage drop along the wire.
Keep the wires reasonably short between the power supply and the display.
When you are wiring the 5V and GND to the strips, I suggest adding 5V and GND to the beginning
and end of each of the 8 separate strips controlled by the OctoWS2811.
