The Parisian club has now secured the prestigious trophy on 14 different times.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup winners after the French winger opened the scoring in the opening stages.
However, Marseille struck two times late to seize a shock lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
