The Parisian club has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league champions and the Coupe de France holders after the French winger found the scoring early on.
However, Marseille struck twice in the closing moments to seize a surprise 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 turn of events, the Portuguese striker grabbed a vital leveler in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
