PSG has now secured the prestigious trophy on 14 different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait 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 between the French league champions and the Coupe de France holders after the French winger found the scoring early on.
However, Marseille struck two times in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
