PSG has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable win in the showdown featuring the French league winners and the French Cup holders after the French winger opened the scoring early on.
Yet, the southern French side fired two times late to take a surprise lead. Initially, 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 grabbed a vital equaliser in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last thirteen seasons.
