x17 R1, purchase 240W slim AC adapter?

Good evening,

I bought an x17 R1 on Dell's Outlet and love the laptop. However, it shipped with the old bulky brick AC adapter. Is there any way to get the official slim AC adapter that shipped with new ones? I see the Dell branded ones online, but even though it's a small thing, I was hoping to get the official Alienware branded adapter.

Thanks!
