PSG has now won the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome 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 match between the French league champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a surprise advantage. First, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the last thirteen seasons.
