What is this connector (MSI GS70)?

I would be interested to know what that plug is or what it's called. This is the power plug of my MSI GS70 laptop. (see pictures)

Thanks for any answers.

Hollow plug.

However, there are differences in terms of the thickness of the center pin, and the total thickness.

A DC low-voltage hollow connector. Are there in zig different sizes, ie inside and outside diameter. If you need replacement, always measure outside and inside.

This is a hollow connector.
