The Parisian club has now secured the season-opening cup on 14 different times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup winners after the French winger opened the net in the opening stages.
Yet, the southern French side fired twice late to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital equaliser in the dying seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a convincing penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
