PSG has now won the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be sailing towards a straightforward win in the match featuring the French league champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times in the closing moments to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past 13 years.
