The Parisian club has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the French league winners and the French Cup holders after Ousmane Dembele opened the net early on.
However, the southern French side struck twice late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 years.
