Power supply recommendation for Ryzen 7 1700 and gtx 1080

Solution
The power requirement is around 350w if you see the top right of your pcpp build. So anything above 450w should be more than enough. However I would recommend a couple of changes to your list.
A SSD will do a world of good to the performance. Blower style cards often have heat issues and usually avoided. Added a case.
