This seems crazy to me. I run an entire home office, sometimes with a reasonably powerful main workstation (enough for things like 3D graphics work), a second PC or laptop, and various server and networking equipment all running at once, and unless we’re also using something power-intensive like a laser printer the entire room doesn't draw 1kW!
