What's your server wattage?

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.

I have four Raspberry Pi 4 running, so that's 15W max each or 60W max total. Usually they consume much much less.

For my main server only... If HP iLO is to be believed, averaging around 130W.

Running: deluge, homarr, jellyfin, lidarr, navidrome, nextcloud, prowlarr, sonarr, whoogle and a minecraft server (VM) on TrueNAS Scale.

As for everything else (my router, switch and DNS/DHCP server, which is a separate machine, you can add another maybe 50W on top of it...

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.

Soggytoast ,

Is that a bios or truenas setting? The CPU is only 35 watt max

Operating system so TrueNAS in your case

About 120W total for:

  • 2 Proxmox hosts with 4 spinning disks between them
  • Opnsense firewall
  • 24 port GbE switch
  • Fiber ONT
  • Unifi AP
vividspecter ,

Systems themselves are all around 5-20W, although the ones with mechanical HDDs obviously add their own idle usage.

About 30 watts for a old Lenovo Thinkcentre with a i5-6500T and 8 GB RAM in combination with a DAS and 2x2TB HDD's. I'm currently waiting for parts for my new server I'm building, a small N100 Mini-ITX board with 4x4TB HDD's that hopefully has a similar power consumption.

15w
Raspberry pi 4 + HDDs

DjMeas ,

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.

Charadon ,

The last time I checked, mine runs at about 5-10 watts usually.

  • Intel i7-3770
  • 16gb DDR3
  • 2 1TB SSDs
Catsrules ,

Are you sure. I was thinking those specs you would be more in the 50-80 watts range.

Charadon ,

Yep, my homeserver spends most of it's time idling, so power management kicks in.

Now when one of my build VMs are running, it'll get up to that range, but that's why I said it runs at 10 watts usually

Nickall01 ,
  • 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

NeoNachtwaechter ,

My real server (Nextcloud/NAS/several more vm's) uses 28 Watts on average. In addition, there is one Pi 4B running, and I don't even know it's wattage.

I'm planning on replacing the real server with a new one, with lots of cores and approx. 50 Watts then.

Djtecha ,

Pi4 tend to stick around 5w

5950x in an matx board with
15 x 3.5in drives
1 x sata sad
1 x optane u.2 drive (pulls like 10watts)
1 x Nvidia A2000
1 x Lsi 9305 16i
1 x 2.5gbe intel nic
3 x 140 mm fans at full tilt

Runs at like 120 watts at idle, like 220 watts with a good amount of work and peaks at like 320 watts if I make it do a lot of work

just_another_person ,

What in the world...

Dafuq you doing over there?

mlaga97 ,

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.

realbadat ,

Let's see...

My servers (tiny/mini/micros) in total are about... 600W or so. Two NASs, about 15-20W a piece.

I spend a out $150/mo in electricity, but my hot water/HVAC/etc are the big power draw. I'd say about $40-50/mo is what I'm spending on powering the servers in my office.

Definitely puts off some heat, but that's partially because it's all in one rack, and I've got a bunch of other work hardware in there. It's about 2 degrees warmer in my office than the rest of my home, but I also have air cycling all the time since it's a single unit HVAC and I need to keep the air moving to keep it all the right temp in the other rooms anyway (AC will come on more often otherwise, even without my rack).

Rizilia ,

Around 100 Watts for

  • NAS with 4x3.5" HDD,
  • Minisforum HM90 for Proxmox with 2x2.5" HDDs,
  • 16 Port TP Link PoE Switch,
  • TP Link router
  • 2x Raspberry Pi 4b

But everything with gigabit speed. Doesnt need more at home

Minisforum HM90 for Proxmox with 2x2.5" HDDs

How did you connect HDDs to that thing?

Rizilia ,

Inside the bottom tray you have two cutouts in order to put two 2.5" HDDs/SSDs in

Well look at that, it sure does. Too bad they don't make those anymore.
