The Parisian club has now secured the prestigious trophy on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, Marseille struck twice late to take a surprise lead. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 years.
