He just stored the power to channel it in someone able to use it.
So Sentry clearly destroyed the Molecule Man able to destroy Lifebringer Galactus with a thought, and shove the previous Marvel Omniverse into a box.
About Owen and the power of the Beyonders:
1) When he got it, he couldn't use it as he could only channel the power into another being and not use it himself.
2) He was stripped of this power when Franklin and Reed used it to remake the Universe.
Everything is explained in those links.
Feel free to crop the scans if that make the explanations easier.

As you saw, Owen can't use the power of the Beyonders, he can just store and then they put "slices" of Owen as an anchor in every universes they remake.
The power of the Beyonders was directed (used) by Reed Richards and shaped by Franklin into different Universes.
