do you need power to ko a opponent?

accuracy is pretty important too.

I've bounced plenty of hard shots to the side of peoples heads without much effect, but i accidentally knocked a sparring partner out with a relatively weak shot that accidentally landed pinpoint on his chin. I was as surprised as he was.

He was also coming foward at the time which andre also pointed out as important. Bruce lee also wrote that catching someone on the way in could almost double the impact like two cars crashing head on.

That is also mentioned in JD's book, the whole two bodies colliding head on generates double the force.
