So ive never really paid attention to the power I consume running various servers over the years but now that ive cleaned up and consolidated im trying to gauge my power draw compared to others.
I run a Proxmox host with 13 HDDs, 6 NVMe drives and 2 U2 NVME drives, a Quattro P2200, RTX A2000, RTX 4070, Epyc CPU, HBA for HDDs, NVMe Card 4x4.
A Synology 2422 with 4SSD, 2 HDDs
A Synology expansion with 8 HDDs
I run about 500 watts off the wall for all this stuff and I think this is the lower end as I wasn’t using the GPUs. That includes a couple switches as well. Very silent runs very cool.
What do other people consume?

All these comments are making me think about how I’d create the minimum power-use homelab. Was looking at 3 year old servers but now I’m thinking just building a low power but powerful system that uses very low power at idle but when in use I’m less worried as it’s more about getting the job done.
Uh, a lot. I haven’t looked in a while, but probably 800-1000w
r730xd with 14 drives, dual procs and 512gb ram
r710 with 8 drives, dual procs and 144gb ram
r510 with 12 drives dual procs and 64gb ram
The heat generated on the back side is pretty high, so thats where my electric bill is going :(
Dell T20, 2x Wyse 5070, Optiplex 3000 thin client. HP 600 g3 that total about 85 watts. A couple gigabit switches for about ten watts.
Trying to keep it under a hundred watts, but I go well over the T20 and/or the HP have heavy load. Luckily none of my workloads use that much CPU so it’s under a hundred watts.
I have crazy expensive California power so with A/C each watt costs about $4 a year.
I just power everything off except a couple of Raspberry PIs when I’m not using it. I did the math and where I live, it’s about $1/watt/year for loads that are on 24/7. It’s just not worth $400/year to power something that usually idle.
My entire rack is currently idle’ing at around 180 watts. That includes a 10 drive Unraid server with Ryzen 7 3700X. Plus I have a Dell mini-PC, HP EliteDesk G3, A older Apple Mac-Mini running Ubuntu server and a Lenovo m720q (OPNSense).
Of course I’ve never looked at how much the network stuff is using such as 2 switches, 4 x Access points, 2 x Raspberry Pi 3s (DNS/Pihole) and ISP provided fiber gateway box.
200w, I think it could be less if I enable c-states (don’t know why I turned them off)
3x optiplex 3070s
4 HDDs
4 APs, 4 PoE cams, 10g switch
about 60W for my server with 384gb ram
2 thin clients for various purposes so about 15-20w there
so about 75-80w for servers
I have a Dell T620 tower and an R720 rack mount. The full rack consumes an average of 12 KWh every day.
Proxmox on both, but I use the T620 mostly as it has 12 x 3.5" bays, and I have 2 x NVME drives on PCI card. It also houses the Nvidia Quadro P2000 GPU.
Consequently, the tower is more useful, quieter, and under utilised.
This Christmas break, I plan to move any VMs I have on the R720, move some RAM to max out the tower, and sell the R720. It has 16 x 2.5" bays and an H720 in IT mode. It will keep 64Gb RAM, 8 x 200Gb SSD, and 8 x 1.2Tb HDDs (and 240Gb SATA SSD boot drive where the DVD used to be) for the new owner.
The plan is to recoup some cash and lower the power draw of my rack significantly.
274W currently.
But I have an Intel Arc A770 and 2 extra Samsung 980 Pro 2TB NVMe disks in an ASUS Hyper M.2 waiting to be installed when I get the time. I will be decommissioning a server when I do that though, so we’ll see what the running costs end up being. Probably slightly higher overall.
4100 VA or about 2650 W…
Not including my office setup, that’s just what’s in the rack. MX7000 chassis with 7x MX740c blades, redundant 40G core switches, a fiber channel SAN, two 48-bay NAS with 10TB drives, and 240v power with a 5000W UPS.
Not including the AC for the garage that the rack is in.
And no, I am not a masochist.
2650 W
My whole flat uses less yearly
How on Zod’s green earth were you able to get your power factor to be that awful?!
Xeon processors in my case
Follow up question: how is your hearing? An actual blade setup would be loud as bombs inside a house.
Actually, the MX7000 is not terrible on noise comparatively. Not silent, obviously, but no worse than a typical 1U server.
Now, having that many compute modules may make that thing loud…
Yep. It’s not so bad. I typically only have 4 or so blades powered on at a time, so it’s not so bad. The MX9116N IOMs I have though require more cooling. Had I gone for the lesser ones, it’d probably be a little quieter.
How did you got an mx7000?
I just calculated this would cost me £8272 p.a. ($10160) to run.
Or €15111 little tiny bitty coins in chocolate/beer country.
Ouchies.
Power costs me $0.09 kWh where I live, so it’s far more affordable for me to run.
What tool is everyone using to measure power utilization?
You can get some good power meters from Ali. They have versions that go into sockets and versions that go around power lines. I have a single socket one, Atorch. They are readable remotely.
850 watts is my normal server rack load, however, with cameras and other switches I’m at 1100 watts 24/7 currently.
Add another 600 watts if I turn everything on in the server rack.
300w including networking on a 3000VA APC

I only use JuggaloWatts. Whoop Whoop!
~200 kWh during the day, ~700 kWh during the night. I stress load at night to heat up my room, literally.
I assume you have a measurement wrong, 700kwh during the night means (in a span of 12 hours) a continuous load of 58000 watts. If not, nice datacenter you got there!
Oh yeah, should not type this comment when I’m sleepy 😴 Watt Hour, not kWh.
Dang, my entire house (including my lab) uses about 1100 kWh a MONTH. You have serious consumption going on.
My bad, only 700 Wh (0.7 kWh, not 700 kWh 😅).
