The Parisian club has now won the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the match between the French league winners and the Coupe de France winners after the French winger opened the scoring early on.
Yet, the southern French side struck twice late to seize a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
