PSG has now claimed the prestigious cup on 14 different times.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the French league winners and the French Cup winners after the French winger found the net early on.
However, the southern French side struck two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last thirteen seasons.
