The Parisian club has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown between the French league winners and the French Cup holders after the French winger found the net in the opening stages.
However, Marseille fired twice late to seize a shock advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned 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 seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
