PSG has now claimed the prestigious trophy on 14 separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the French league champions and the French Cup holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice late to take a shock advantage. Initially, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
