PSG has now secured the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
However, Marseille struck twice in the closing moments to take a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently 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 dying moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
