Acer TavelMate 630 ac adapter connector size!

I'm trying to buy a new adapter for my laptop but it is a little confusing. I looked over the internet for one compatible but I get three different sizes when it comes to the connector size. Which one should I buy? Are they all compatible with my laptop? Thank you in advance for your answer.

I bought the Sparkle Ultra Slim 90W, and it comes with all three of those tips, so you could get that one and be covered. The Ultra Slim 65W also comes with the tips.

 

I tried to find what is the connector original size on acer website but unfortunately they don't publish this kind of information and I don't understand why.
