PSG has now won the prestigious trophy on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, Marseille struck twice in the closing moments to take a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
