How to choose a replacement DC power connector
My guess would be, that the manufacturer chose the power brick first because its rated power is quite high. And that was the connector they ended up with.

If you still have the damaged logic board, you might want to find out, if the two 24V lines are tied together on the board or if they were used separately. They could be two separate power rails, but my guess is that they used this to reduce the current per contact, as contacts for 9.2A is quite the requirement in a compact space.

I'd use the Molex 8981 series, the ones used on 3.5" HDDs, they are rated for a current of 6.5A per contact, have 4 contacts and are readily available.
