PSG has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions seemed 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 in the opening stages.
However, Marseille fired two times in the closing moments to take a shock advantage. First, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to seal a 4-1 shootout win.
The record champions PSG, who faced 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 thirteen seasons.
