The Parisian club has now won the prestigious cup on 14 separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the net in the opening stages.
However, the southern French side struck two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout 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 trophy for the twelfth time in the last 13 years.
