I’m in the process of wiring a home before moving in and getting excited about running 10g from my server to the computer. Then I see 25g gear isn’t that much more expensive so I might was well run at least one fiber line. But what kind of three node ceph monster will it take to make use of any of this bandwidth (plus run all my Proxmox VMs and LXCs in HA) and how much heat will I have to deal with. What’s your experience with high speed homelab NAS builds and the electric bill shock that comes later? Epyc 7002 series looks perfect but seems to idle high.
15w Raspberry pi 4 + HDDs
125W (Less than $15/month) or so for
- Ryzen 9 3900X
- 64GB RAM
- 2x4TB NVMe (ZFS Mirror)
- 5x14TB HDD (ZFS RAID-Z2)
- 2.5GBe Network Card
- 5-port 2.5GBe Network Switch
- 5-port 1GBe POE Network Switch w/ one Reolink Camera attached
I generally leave
powerManagement.cpuFreqGovernor = "powersave"in my Nix config as well, which saves about 40W ($4/mo or so) for my typical load as best as I can tell, and I disable it if I’m doing bulk data processing on a time crunch.Actually if anyone has advice I’d love to hear. My server is a b450 mobo with an athlon 320ge. Even with no hard drives spinning it uses 65watts. I don’t understand how it is possible. 6 hard drives bring it to 85-90. Running truenas if it matters
I keep it off most of the time to safe power, I was expecting especially with such a cou much lower wattage, like under 20 idle. My assumption is the power supply can’t get low enough.
What CPU governor are you using? I saved about 40W idle powerdraw switching to powersave vs the default on a Ryzen 9 3900X.
Is that a bios or truenas setting? The CPU is only 35 watt max
Operating system so TrueNAS in your case
- Fujitsu motherboard
- Intel pentium G5600
- 6 HDD (4 x 4 TB 2 x 8 TB) spinned down
- 2 SSD for proxmox
- 6 CT and no VM for now
it runs at 16W mostly idle
I’ve got a 3 node Proxmox/ceph cluster with 10G, plus a separate Nas. They are all rack mount with dual PSU. Add in the necessary switching, and my average load is about 800w. Throw my desktop (also on 10G) into the mix and it runs 1.1kw.
That’s roughly $50-60 extra in electricity costs for me monthly.
I ise about the same. But that is more due to the hardware I got being a bit older. 2 dell R710s 1 R510 and a custom build server. Everything is still 1g. In my case electricity is not a big deal due to solar. We produce much more then we can use our self.
I’m afraid of dumping 500+ watts into a (air conditioned) closet. How are you able to saturate the 10g? I had some idea that ceph speed is that of the slowest drive, so even SATA SSDs won’t fill the bucket. I imagine this is due to file redundancy not parity/striping spreading the data. I’d like to stick to lower power consumer gear but ceph looks CPU, RAM, and bandwidth (storage and network) hungry plus low latency.
I ran proxmox/ceph over 1GB on e-waste mini PCs and it was… unreliable. Now my NAS is my HA storage but I’m not thrilled to beat up QLC NAND for hobby VMs.
My 10G is far from saturated, but I do try and keep things using RAM where possible. I figure that with 100gb of DDR4 in my main server, that should be able to provide enough speed for a 10G link.
I’ve got ceph running on Intel Enterprise SSDs, so they are pretty quick.
I also tried running ceph on 1G. I found it unreliable as well.
Would be around 300€ in Germany, on a cheap contract. Limiting myself to one combined NAS/application server atm, with the others turned on only if I want to try sth out.

Average load 800W is 0.8kW24h30d=576kWh/M
Which is over 172€ on a 30ct/kWh contract.
Wow! I’m paying 10.5¢/kWh for electricity at home here in the US; it’s a little below the national average but not dramatically.
Yeah, we pay a lot. We also got one of the lowest downtimes regarding electricity, on average approximately 10minutes per year…so that’s kind of a (small) advantage you get for the premium price
I have a small setup for some self hosted apps and media.
- Beelink Mini S.
- 2 external 5TB drives.
- A USB fan used as an exhaust because the SSD inside gets a bit warm.
I think total power is about 30W.
The load on my UPS is around 100-140 watts. That includes my server, firewall, switch, starlink and a unifi access point. I would love to get that power consumption down. I only get 4-5 hours of runtime on battery. Also, the room it’s in is small and it gets really hot in the summer time.
7W I think
Mine is about 8W on average.
It’s an Odroid H3 that runs Nextcloud, Jellyfin, AudiobookShelf, a bunch of websites and Home Assistant.
It has 2x Sata SSD’s connected.
This setup is not high speed at all, so it’s not what you asked about. I just answered the headline question. ;)
If any air ventilation fan turns on in the house it uses at least 3x that power, so I don’t calculate the price on my servers power draw as it almost not noticable.
I use a Ryzen 5900x, RTX 3080, 2x 10Gbit sfp+ NIC, 128GB ECC RAM, and only 2x 20TB drives at the moment.
For my gateway, I have an Intel N6005 box, I have a managed 2.5/10Gbit switch, and I have a wifi AP.
I have a ton of Proxmox VMs and containers.
All that hovers between 140W to 180W
I recently removed my 25Gbps PCIe dual port cards from my 2 servers because they were using 20W more. My entire rack including 2 UniFi PoE connections uses 90 W now (so 110 W just for having 25 Gpbs).
There is some heat from such cards, but usually it gets transported outside fine. The ones I bought did not come with a fan. I think you cannot operate them without one. The heat sinks get very hot.

My pi costs probably around 20 a year lol.
82.2W average for which I pay 144.6€/a at the moment. That’s for a Ryzen 7 3700X, some hard drives and SSDs and the fiber connection to my basement. I outsourced 90% of media consumption to a VPS though, that’s another 84€/a.
I run a NUC11 so about 10W. 15-20€ per annum assuming a single tariff at 0.17€ per kwh. It can use up to 30W but only during heavy load which may be like 8 hours a week. But electricity is also cheaper during off peak hours so it averages to about that (we have 5 tariffs).
Load is NAS, media server, homeassistant and a usb zigbee router, *arr stack.
Power usage was my main concern and wanted something eco friendly.
