The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring early on.
However, Marseille struck twice in the closing moments to seize a surprise advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
