The Parisian club has now won the season-opening cup on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the French league winners and the Coupe de France holders after the French winger opened the net early on.
Yet, the southern French side fired two times late to take a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a vital equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, 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 12th time in the past thirteen seasons.
