The Parisian club has now claimed the season-opening cup on 14 separate times.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown between the French league winners and the French Cup winners after the French winger opened the scoring in the opening stages.
However, Marseille fired twice in the closing moments to take a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently 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 moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a convincing penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
