The Parisian club has now claimed the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck two times late to seize a shock lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past 13 years.
