The Parisian club has now won the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout 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 straightforward triumph in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the net early on.
Yet, Marseille struck twice in the closing moments to seize a surprise advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
