IIRC the RPi4 states 5.2v. but what is 0.1v between fiends.
I use old recycled 'Traco Power' 5v 5A smpsus and supply power
direct to the Pin Headers using two power and two sense cables. I
had a good free source of the Traco, long gone, sadly.

my experience is that most wall warts provide 4.99
volts and the rpis want 5.1

The voltage drop in most or all USB cables is too much.
Hearing about all the 'high current' capability of USB C
cables, I ordered some SHORT one and USB C to micro adapters
for my old PI's.
Hopefully a solution.
I have dozens of 5v wall warts and none seem to work. The
wires in normal USB cables are way too small for several
amps.

No problems here with supplies provided with my Pi4's.

Ideas?
