PSG has now secured the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the net early on.
Yet, Marseille fired twice late to take a surprise lead. First, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the 12th time in the past 13 years.
