The Parisian club has now secured the season-opening cup on 14 different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France winners after the French winger opened the scoring early on.
However, the southern French side struck two times in the closing moments to seize a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
