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.
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.
Jiggawho?
80W for me in R730 running various VM and most of the time are just idle.
around 350W at the moment, but I’m in the middle of a data migration.
i7-8700 whitebox VM host
2x HP N54L with 4x 8TB SAS drives, one of them also has 2x 500GB SSD and 2x 500GB HDD

a couple of UPSes
Huawei LTE router
probably some other stuff that I’ve forgotten
Will likely be adding a Dell Optiplex mini PC soon

45-50W during the day at home, 20-25W during the night as I shut down my server. Swapped the PSU in that server which reduced the load by 10W, the previous one apparently was way oversized.
200-300W at my parent’s basement permanently where I keep my storage servers with 36 HDDs in total. They have PV on the roof, a large battery in the basement and don’t want to put excess power back into the grid so I was allowed to move my large servers there.
~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 😅).
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.
300w
The Z620 is incredibly quiet for as powerful as it is. I have one I use running ESXI to virtualize network equipment for study
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.
Idle ~1.2kw underload reasonably 2.5 to 3kw? Haven’t really stress tested everything to see where I sit at 25% intervals yet. Still rebuilding my rack, office, and support pcs right now. Will have a better idea of exact figures later this week. Averaging 85kwh/day for the house. Everything either has extremely specific low power tasks such as home assistant or truenas or handles vm, production environments, game servers, or gaming for the most part.

Anywhere between 250W-1000W depending on load. Daily average is about 400W right now.
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
