The Parisian club has now secured the season-opening cup on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout 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 showdown featuring the French league champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
However, Marseille struck twice late to seize a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
