PSG has now claimed the prestigious trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times late to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
