PSG has now won the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league champions and the Coupe de France winners after the French winger opened the net in the opening stages.
However, the southern French side struck twice in the closing moments to take a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the past thirteen seasons.
