The Parisian club has now won the prestigious trophy on 14 different times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to overcome 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 straightforward win in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, Marseille fired twice in the closing moments to take a shock advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
