I tried to power my RPi5 with the green connector, on the backside, with a 5V/6A (30W) power supply, but the RPi doesn't work properly; the boot sequence hangs before the end. When I boot with the USB C power supply (the RPi model, 27W) everything runs smoothly. I have an M.2 NVME disk, a SD card, an external USB3 hard disk (5TB)
Is the power supply 5V/6A not enough ???
