PSG has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, Marseille struck twice late to take a surprise 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 events, the Portuguese striker grabbed a crucial leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to complete a 4-1 penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
