PSG has now secured the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown between the Ligue 1 champions and the French Cup holders after the French winger found the net early on.
Yet, the southern French side fired two times late to seize a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
