The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward win in the match featuring the French league winners and the Coupe de France winners after the French winger found the net early on.
However, the southern French side struck two times late to take a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions PSG, who met 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 seasons.
