The Parisian club has now won the season-opening trophy on 14 different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring early on.
However, Marseille struck twice late to take a shock advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
