. My nas is my old CPU and mobo with some cheap gpus and 3 Seagate nas drives. I have a Rx 580 for the host os and a 2080ti water-cooled for vms. Idle it uses around 180w and around 320 with Plex and immich going full bore maxing out my 5950x. I haven't figured out what USB controller I have to pass through to use USB devices in my vms so I haven't really been able to test the power draw while running a VM with aida64 and furmark running so I don't know the max it'll pull. In my area it looks like my nas at an assumed consumption of 200w cost around $250 USD a year to power. Ouch.
