A powerful GPU working hard is probably the hungriest component you have, on par with powerful CPUs. 50 to 200W isn't crazy for a GPU. | |||

Yes, they may draw 1000 or 2000W. | |||

Computers
tl;dr:
- Assume 40W or more for laptops, idling at 10W with things dialed down
- 150W or more for desktops, idling at 100W (can be much less, if specialized)
- counting basic monitors (larger and brighter may add more)
- most gaming machines don't go over 300 or 400W when working hard
