PSG has now won the season-opening cup on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown featuring the French league champions and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood scored 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, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
