PSG has now claimed the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable win in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the net early on.
However, Marseille fired twice late to seize a surprise advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen years.
