The Parisian club has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, Marseille fired two times late to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
