For R4 power consumption testing, a 12V/2A power supply is sufficient; for R4 + BE14, a PD30W power supply can handle modest loads; however, if all accessories (R4 + BE14 + 10G Ethernet port + 5G + SSD) are included, a power supply of 45W or higher is recommended.

thank you. I see you were using an usb-c power. What do you suggest one buys for a 45w power supply?

Oh, that is more than I expected. Those wifi chips really need a lot of energy.

I’m currently using a 20V, 1.2A power supply, so 24W max, and use the wifi nic, GPON SFP module and maybe an nvme SSD. Maybe I need to remove the SSD or upgrade my power supply again. Just ordered it two weeks ago, because I thought 24W would be more than enough. I guess I was mistaken.
