The Parisian club has now claimed the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 winners and the French Cup winners after the French winger found the net in the opening stages.
However, the southern French side struck two times late to take a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
