The Parisian club has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
Yet, the southern French side fired two times late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen years.
