PSG has now secured the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France holders after the French winger found the net early on.
Yet, the southern French side struck twice in the closing moments to take a shock lead. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
