No idea!
Going from publicly-available info though:
Rpi4B - 6.4W max (more like 5 in real world usage)
Cpu case fan - 1.4W
2x SSD - ~6W each
13.8 to ~18 depending on what the SSDs are pulling i guess. I use it as an *arr seedbox and plex server (up to 1080p h264 works flawlessly!) as well as nextcloud
