PSG has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, Marseille struck twice late to take a shock lead. 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 remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
