PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired twice late to seize a surprise advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the 12th time in the past 13 seasons.
