The Parisian club has now secured the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck twice late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
