PSG has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a shock advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last 13 years.
