I would recommend to use your 100watt PSU on everything, I looked at all your pictures and see you use a separate 5volts USB connector for powering your raspi4. Which isn't necessary. So make them one, or use the 50watts psu separate for the pi only, then ground everything together (use more ground pins on the PI 》》》 and very important!! Apply +5volts and gnd to BOTH sides of your ledstrip... and measure after that with your multimeter the voltage out of PSU 》》 not more then 5 volts dc under load. Your ledstrip should draw about 12,5 Amps with full brightness so there's still enough power for the USB port and pi.
First try measure and do this steps before you go on. Basics has to be good. Your connection overall is okay, not really clean but technically correct :classy:
Thank you for the response. Completing the DC loop fixed the issue. I had tried that the previous day but must have had another issue going at the time.
Ya, the wires are due for some fixing up when I put everything together in a project box...I just kind of threw it together for testing. Thanks again!
