PSG has now won the prestigious cup on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the French league champions and the Coupe de France winners after the French winger opened the scoring early on.
Yet, the southern French side struck two times late to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last 13 years.
