The Parisian club has now won the prestigious cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France winners after the French winger opened the net in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial leveler in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 years.
