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 overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the net early on.
However, the southern French side fired two times late to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
