PSG has now secured the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the French league winners and the French Cup holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck two times late to seize a surprise lead. 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 turn of fortune, the Portuguese striker snatched a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
