PSG has now secured the season-opening cup on 14 separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable triumph in the match between the Ligue 1 winners and the French Cup holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck two times late to take a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
