PSG has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match between the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, the southern French side struck two times in the closing moments to seize a shock advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing penalty victory.
The record winners 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 won this trophy for the twelfth time in the last thirteen seasons.
