I am getting my new laptop shipped to my house soon.

Currently it will come with 180W + 240W = 420W

Is it possible to use the following combinations?

2X 180W = 360W

2X 240W = 480W

1X 330W = 330W

I am very OCD and I don't want to see 2 different size. How does the laptop behaves? Does it read total W or needs to have 2 power supplies? If it needs 2 I would assume 2x 480W would work but will it damage the laptop?
