The Parisian club has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. Initially, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen years.
