The Parisian club has now won the season-opening trophy on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the match between the French league champions and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, Marseille fired two times in the closing moments to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital leveler in the final seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
