PoE Single Board/Micro/Mini Computer/Server (lemmy.world)

I have an 8gb Raspberry Pi 4 that has been a workhorse for years. I keep it for my not intense but essential networking purposes, NetBoot.xyz, Homepage, etc., because I can run it over PoE (edit: Power over Ethernet), so it is always on as long as my network is up.

It is growing long in the tooth, and I find myself wanting to replace it with something a bit more capable. Looking at the 8gb Pi 5 at $80 plus another $30 for a PoE hat, I wonder if there is something out there that would be a better value for running PoE? Can you convert a micro pc over to PoE? Does anyone have any recommendations for computers that run off PoE or can be converted to PoE?

Webpage loads are slow, especially images, netboot is a bit slow. I'm sure it's i/o bottleneck and that everything is running in docker containers. I could probably optimize things a bit better, I just don't have that kind of time for these projects, and getting an old dell micro would be faster than what I have. but they don't run on PoE+ that I know of.

… they don't run on PoE+…

They do not; the power requirement is too high. You’re not going to find a computer with a “desktop class” CPU that can be powered via PoE.

Laptop class CPUs can though. AMD Ryzen chips are useful all the way down to 15w. There is a post in this thread of a mini-PC with one and PoE. Real happy that exists.

Got that link? I just looked and don’t see anything in this post linking to a computer with a desktop class processor that will run on PoE.

Thisin! Links to a few min overview of a Ryzen based PoE mini-pc.

I think pi 5 might be pretty good for you.

If I am not mistaken, they improved the io A LOT in the pi 5.

Also, you might be able to use the old HAT, at least it worked with pi3 poe hats on pi4.
