The Parisian club has now won the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match between the French league champions and the Coupe de France winners after the French winger opened the scoring in the opening stages.
However, the southern French side struck two times late to seize a shock advantage. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a vital leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
