The Parisian club has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the French league champions and the Coupe de France winners after the French winger opened the net early on.
Yet, Marseille fired twice late to seize a shock advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the past 13 years.
