PSG has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times late to take a surprise lead. First, 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, Goncalo Ramos snatched a crucial equaliser in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the last 13 seasons.
