PSG has now won the season-opening cup on 14 separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck two times in the closing moments to seize a shock lead. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive 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 penalty win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
