user61599: I've got a 200 LEDs strip of sk9822's hooked up to a 5V 8A power supply.
As expected, at full white, there's considerable voltage drop and the far end of the strip turns from white to amber.
I wanted to hook up another set of V+ and GND at the far end of the strip, but doing so trips my psu? The strip blinks full white as a result.
Hooking up ONLY GND or ONLY V+ at the far end significantly improves the drop off where only the middle of the strip turns slightly amber-ish.
But! I do notice a faint buzzing from the PSU if I do this.
Am I doing something wrong here?

user61618: Put a diode to every psu cable or just take only one psu but make a connection between the input and the far end eith a cable of more than 0,5 mm^2... Spesker csble or so. 
Problem with two psu is: one gives 5,00 Volt,  the other 5,05... And there is s power of 0,05 Volt / 8 Ampere running.  
Second problem can be the influrnce of different PSU switching frequencies.
