If you visit your-domain.com/wp-admin/admin.php?page=w3tc_install W3 Total Cache will show you all the additional configuration information that you need. Included in that information will be some Nginx configurations which I’ve also listed below. Copy and paste it into your WordPress installation’s Nginx server block (a.k.a VirtualHosts).
