PSG has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match featuring the French league winners and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired two times late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
