PSG has now claimed the prestigious cup on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille fired two times in the closing moments to take a shock lead. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
