Super Power-Efficient ITX Nas CPU/Motherboard? (lemmy.world)

I've got a NAS built in a Node 304 mini itx case that works great, but uses a ton of power. In Unraid (the OS for my NAS) there is some kind of issue with the Ryzen 3900x processor that I'm running that means I have to disable all sleep states - so it's always at it's 100W TDP. Power is super expensive where I live so I'd love to find something more power efficient.

Does it make more sense to buy a more recent(ish) 5th gen ryzen in hopes that the sleep states will work, and thus save money by keeping my existing motherboard?

Or I could go with something a bit more interesting. I've seen on Aliexpress motherboards with mobile CPU's soldered which are very power efficient. For example the N100 has an insane 6W TDP and comes on special boards with lots of sata ports and 2.5G networking (link). The worry with the n100 though is that it only officially supports 16G of ram which might not be enough for zfs.

Any thoughts? Is anyone running a power-efficient build who could throw some advice my way? Thanks!

You're right and that's exactly my plan! I'm going to get 2 20TB drives the next time I need to upgrade, that way I can keep the number of drives low.

With my current power usage and energy prices I'm paying $280 per year for this server alone, so I'm pretty well incentivized to replace parts (particularly since I can sell the parts I'm replacing to offset even further). With my current plans I'll see a positive ROI within a year almost guaranteed
