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.
I have a 50amp 3 phase line feeding my mini data center. Currently only using 5 amps according to the pdu.
300w including networking on a 3000VA APC
|Last Battery Transfer Line voltage notch or spike |Internal Temperature 21.6°C|Runtime Remaining 2hr 1minute| |:-|:-|:-| |Load Power 13.0 %Watts|Apparent Load Power 11.7 %VA|Load Current 3.1 Amps|
Anywhere between 250W-1000W depending on load. Daily average is about 400W right now.
80W for me in R730 running various VM and most of the time are just idle.
As in average? 1491W 30 day average according to the power meter. Fully loading everything is around 5kW iirc though that doesn’t really happen. Highest in last 30 days is 3774W peak and I think that’s when I accidentally shut down the UPS so everything was booting at the same time after. I don’t think I ever go over 3kW in normal circumstances.
Using 5 storage servers, 2 of which are storinators and 3 supermicros. And then two compute nodes which are Proliant DL380, g10 and a g11 that I just bought last week. Plus ofc some network gear which isn’t really anything too fancy, it’s just two routers, which while they do do PoE, I don’t use it so they’re not really high power or anything.
About 50 watts. I downsized a few years ago, got rid of the unnecessary larger servers, moved to Intel nucs and a 4 disk nas for centralized storage. Was no need to run large servers at home, I play with them at work.
I run proxmox on the nucs with my servers in vms, each nuc has 16gb of ram and performance is fine
I draw around ~175W as normal 24/7 load.
It includes:
- CloudKey gen 2 pro
- USG-4
- 48 Port Switch
- 3 APs
- 2 Lenovo SFFs (have to check specs later)
- NAS (custom build SSD based)
- 750VA UPS
735W 24/7, some HW on the way, i might exceeed 1KW
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.
My entire rack idles around 160W, which includes switches, router, 3 cameras, 2 hotspots, and a server with a Xeon 2680 v4, 100GB of RAM and 50TB of storage, along with a 1650 Super for transcoding etc.
Wow! That seems really efficient. What server/network equipment are you using?
It’s nothing special. Server is custom, built in an Inter-Tech 4U case with 8 hotswap bays, using an x99 motherboard.
Networking is Ubiquiti, with a PoE-capable switch to provide power to access points and cameras.
A big difference was made by making ProxMox use a power plan that lets CPU go idle or clock down, which I think was good for like 20-25 watts. My Windows 10 VM is less responsive in RDP, but otherwise doesn’t seem affected, and the Linux-based VMs don’t seem to care.
50 watt idle
Debian OMV Asus from 2015 Laptop
Proxmox VE HP g3 mini with Mediasonic Probox 4 bay das and handful of external hdd
Router from ISP
cheap 5 port gigabit TPlink switch
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.
Lenovo Tiny m700 8th Gen i5, 32GB ram, USB SSD boot, Sata SSD storage, USB SSD Backup, extra m2 2.5ge nic to replace the wifi card. Run Proxmox with pfSense. About 11-15 Watts average. Spikes to 50 when running a batch job.
Considering a ZimaBoard but needs more RAM for the batch job.
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.
