The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown featuring the French league champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck two times late to take a shock advantage. Initially, 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 events, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
