The Parisian club has now secured the season-opening trophy on 14 different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the French league winners and the Coupe de France holders after the French winger found the scoring early on.
Yet, Marseille struck twice in the closing moments to seize a surprise advantage. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
