Graphics Amplifier bought in Sweden

Hi! I'm wondering if the Graphics Amplifier bought from the Swedish Dell store works with my Alienware 17 R2.

It says when I look in the store that it works for Alienware 13 but it doesn't state any other laptop, just the one, which got me confused. Looking further at the US store the manufacturer and Dell parts differ from the Swedish one.

The store name: Dell Alienware Echo-Series Docking Station - 460-watt - for Alienware 13

This is what the parts from the Swedish store are called:

Manufacturer Part FK27J

Dell Part 452-BBQP

And this is the US parts which says that it works with my laptop:

Manufacturer part 8W39R

Dell part 452-BCFE

So does the Swedish one in fact work with my 17 R2? If it does, you might want to update the description for the Graphics Amplifier to state all compatible laptops other than the Alienware 13.

Thank you!
