PSG has now claimed the prestigious trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the match between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
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 turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a vital leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
