The Parisian club has now won the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after the French winger found the net in the opening stages.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. First, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
