PSG has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, Marseille struck two times late to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the last 13 seasons.
