The Parisian club has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired twice late to take a surprise advantage. First, 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 fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last thirteen years.
