The Parisian club has now claimed the season-opening trophy on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck twice in the closing moments to seize a surprise lead. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last 13 years.
