PSG has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, Marseille struck two times late to seize a surprise lead. 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 turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
