PSG has now claimed the season-opening trophy on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the French Cup winners after the French winger opened the scoring early on.
Yet, the southern French side struck two times late to take a shock advantage. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing penalty win.
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 12th time in the last thirteen years.
