PSG has now secured the prestigious trophy on fourteen separate times.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the French league winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
