PSG has now won the prestigious cup on fourteen separate times.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match between the French league champions and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck twice late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
