The Parisian club has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired two times late to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing shootout win.
The record champions 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 12th time in the past thirteen years.
