The Parisian club has now won the prestigious trophy on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side fired two times in the closing moments to take a shock lead. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to complete a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
