PSG has now secured the season-opening trophy on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a shock lead. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 years.
