The Parisian club has now secured the season-opening cup on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, Marseille struck twice in the closing moments to take a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the final moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time 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 competition for the twelfth time in the past 13 seasons.
