Powering 1920 leds with 32 strips of 60 ws2812b led strips each (32 meters)
The wiring of the power depends on the layout of the strips, if they are connected exactly like in the image, i would switch build a ring supply (powering both sides of the strips.

Please be aware of the following:


5V, 96A is no joke in terms of security. If the wires touch, there will be a huge arc.
5V 96A requires large wire (like 25mm2)
Each strip of 60 LED's requires 3.6A, check if the strips are made for this current
Check if its possible to drive 1920 led from one data pin. Shifting out data for 1920 led is around 76.8k bits of data
