The one you linked does not have the PC receiver. It is a Xbox 360 controller bundled with a charger.
The wireless Xbox 360 controller with a PC receiver it is sold in a red box (
like this one). Be careful because the "PC version" of the wired Xbox 360 controller is also sold in a red box. The Xbox 360 versions of the controller are sold in a green/white box (and the wireless one does not include the PC receiver). The controller itself is the same (PC/Xbox 360 versions).
The original Microsoft PC receiver has "Microsoft" written on it.
The Chinese PC receivers that I saw have "Xbox 360" written on them.
