PSG has now won the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to seize a surprise lead. First, 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 events, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 seasons.
