you can buy the wireless adapter for the controller. but there are always a ton of issues with them. there are 100 new threads a day here asking for help getting it working.
i'm sure many get them working fine but clearly many more do not. i use a WIRED XB1 controller on my pc and have never had a single issue with it. i'd go that rout myself sine you're not sitting very far away anyway. 9 ft cable is plenty long enough
