The Parisian club has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the Ligue 1 winners and the French Cup winners after the French winger opened the net in the opening stages.
Yet, the southern French side struck twice late to seize a shock lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the last thirteen seasons.
