PSG has now secured the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille fired two times in the closing moments to take a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen seasons.
