The Parisian club has now secured the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the French Cup winners after the French winger opened the net early on.
Yet, the southern French side struck two times late to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen seasons.
