A trained powerlifter probably exerts a few kW on a heavy lift, but only for a second or two.

~3000 watts for 0.75 seconds (not counting pauses)

Talakhadze's 267 kg clean & jerk from 2021 is somewhere well north of 5kw output (I can't find hard numbers, but possibly even like 7kw) for fractions of a second during the second half of the clean. It's wild stuff.
