The Parisian club has now claimed the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, Marseille fired twice in the closing moments to seize a surprise lead. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
