PSG has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, the southern French side struck twice late to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a convincing penalty victory.
Now 14-time winners 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 competition for the 12th time in the last thirteen years.
