The Parisian club has now won the prestigious trophy on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille fired two times in the closing moments to seize a shock advantage. Initially, Mason Greenwood converted 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, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing penalty victory.
The record champions PSG, who faced 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 seasons.
