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?

Two small Synology units (DS120J and DS218+ with attached usb drives for backup), five-port gigabit switch and a modem router, in addition to a Proxmox host (HP 800 G3 mini) runs at about 40W with spun down hard drives, and somewhere around 50W when these are being accessed.

The Synology units automatically shut down at night, at which point the power draw drops to 24W.

It all comes down to about 0.85-0.9 kWh per day.

Assuming a price of 30c/kWh means that even this comparatively small power use comes up to 10€/month or so.
