The Parisian club has now won the season-opening trophy on 14 different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a surprise advantage. First, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past 13 years.
