The Parisian club has now claimed the prestigious cup on 14 separate times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille struck twice late to take a shock lead. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
