The Parisian club has now claimed the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille fired two times late to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
The record 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 thirteen seasons.
