PSG has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup holders after the French winger found the net early on.
Yet, the southern French side fired two times in the closing moments to take a shock lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen years.
