what is the minimum weight required to be able to throw devastating knockout punches?

pic related is sergey kovalev; a slav with incredible punching power. he only weighs 175 lbs and looks dyel but all of his punches are capable of ringing some serious bells

weight helps but its mainly about technique

It's often the skinner fighters with a long reach that generate the most power, e.g.,Tommy Hearns

While tommy hearns has godly hands mike Tyson, rocky Marciano and GGG is who I think of when talking about power

literally just and some genetics play a role, some people just naturally have more explosive strength, not that i cant be trained but being a natural helps. Also hand size can play a big role.

muscle mass coupled with reach and leverage

It's hard to explain, but being a knockout artist is kind if a gift you're born with mixed with luck.

Knockout punches are a gift, you can train as hard you like but you can never punch with the giants of boxing like Shaver or Foreman

This. There are two things you can do to increase your knockout power.
>Improve your technique
>Chop wood (seriously, as in with an axe)

I'm 150lbs at 5'7", fairly low bodyfat, 67.5" reach.

I may be short but I think I could break someone's nose/jaw with one punch.

I punch my hand relatively lightly and it hurts, getting hit in the face by a punch as hard as I could throw would be devastating. I could only imagine how powerful a punch from someone 6'5" with the same relative power as me would be.
