PSG has now won the season-opening trophy on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck two times in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial leveler in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 years.
