The Parisian club has now won the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to get past 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 straightforward win in the showdown featuring the French league champions and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, the southern French side struck two times in the closing moments to seize a shock 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 remarkable turn of events, Goncalo Ramos snatched a crucial equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the last 13 years.
