Controlling 8 led strips

Using Arduino LEDs and Multiplexing
1

I'm trying to scale up this project (Weekend Projects - Android-Arduino LED Strip Lights - YouTube) to instead control 8 5m led strips. Using a 24 channel PWM signal breakout board. These are the strips (https://www.aliexpress.com/item/SMD-5050-RGB-LED-Strip-5M-10M-15M-12V-30-leds-m-Waterproof-Flexible-LED-Tape/32918119847.html?spm=a2g0s.9042311.0.0.143c4c4dX2jbb3) which will use 1.2A per 5m roll. I plan on having 8 5m rolls in parallel, so what is the best option for powering these strips? Is this schematic attached the right way to wire this circuit? The battery is meant to represent a 12v source, the resistors are meant to be 1k Ohm.

which will use 1.2A per 5m roll

What makes you say that?
They will consume more than that. They supply a 6A power supply which is more like it.
