PSG has now won the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the French Cup winners after the French winger found the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a surprise lead. First, the English forward scored from the penalty spot, before the defender 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 final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen seasons.
