PSG has now claimed the season-opening trophy on 14 separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to take a shock advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen seasons.
