The Parisian club has now secured the season-opening cup on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times late to seize a shock lead. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
