Replacement AC adapter for RT-AC88U

[Garrus]

I just bought a used RT-AC88U router that didn't include the AC adapter. Now I have been looking for an original Asus AC adapter for this router not to accidentally damage the router with a poorly built or wrong cable in general. While I've been searching for the right AC adapter, I have come across some different models of the adapter. I know so far that this router comes with this specific AC adapter model ADP-65GD B but another model has the exact same specs for all I know but may be only for laptops(PA-1650-78). Which of these models is the most compatible with this router and does this router only come with the model ADP-65GD B or also with some other models? Also is it a 65W adapter?
