The Parisian club has now secured the season-opening trophy on fourteen different times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck twice in the closing moments to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a convincing penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
