The Parisian club has now won the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock lead. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 seasons.
