I get low power on boot and often it corrupts the boot file and I have to reimage the card. The power supply is a good supply. I think the limiter and the fact it also powers the monitor could be the issue? Any suggestions. Or do you think something else is causing it? I have had this issue on and off. Do you think the monitor is drawing to much power? Should I wire the supply to the 5v gpio side so it doesn’t go through the limiting chip?Before looking at a new power supply it might be worth looking at the cables. Lots of USB cables are a bit skinny and can cause a lot of voltage drop during power spikes.
