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.
Server (Ryzen + 3 HDDs + 2 SSDs) - 50W
Networking (USG + Unifi AP + Mi router as a second AP + switch) - 20W, maybe a bit less
70W in total
My wife says I produce 100 gigolo watts a day but I think she’s just being nice
The gigolos aren’t just for you.
Yeah, save some gigolos for the rest of us!
80W for me in R730 running various VM and most of the time are just idle.
735W 24/7, some HW on the way, i might exceeed 1KW
Anywhere between 250W-1000W depending on load. Daily average is about 400W right now.
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.
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.
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.
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.
Around 90-100W typical for the part of my lab actually powered on. That is my NAS (60W typical) that has five 12/14 TB hard drives attached to a C2750 and my VM Host (35W typical, but bounces between 20W and 40W), which has a couple of SSDs attached to a R7 1700.
A pc, unifi usg 3p, cloudkey gen 1, usw-16 gen 2 what run about 100 watt with pc in stanby (not using and monitors off), 200 watt when I use my pc
I’m hitting just under 5000 watts or 40 amps at 120v. Winter will be warm this year 😎
