PSG has now won the prestigious trophy on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after the French winger opened the net in the opening stages.
However, the southern French side fired two times late to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to seal a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen years.
