Pretty much all hardware comes with clear instructions and warnings about it. Without getting too technical I say that I have a 3A PSU the runs fine at least for me however quality of PSUs is a different story. It's a RockPro64 paired with a dual port PCIe NIC however I would recommend higher rated one if you plan to attach non external powered USB devices.

Well, at least u-boot2021.01 has all the needed support to boot a rockpro64 or pinebookpro from nvme/sata/usb/sd/mmc/net.
If you put u-boot into the SPI-flash it will boot from any of the above media.
