PSG has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France winners after the French winger opened the scoring in the opening stages.
Yet, Marseille fired two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
