PSG has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck twice late to take a surprise advantage. Initially, the English forward scored from the spot-kick, 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 equaliser in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen years.
