The Parisian club has now won the prestigious cup on fourteen different times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the net early on.
However, Marseille fired twice late to take a surprise advantage. 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 remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last 13 seasons.
