How Many Jigowatts Do You Use? (alien.top)

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?

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.
