PSG has now claimed the season-opening cup on 14 different times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout 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 sailing towards a straightforward win in the match featuring the French league champions and the French Cup winners after the French winger found the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock lead. First, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete 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 trophy for the twelfth time in the last 13 years.
