PSG has now won the prestigious cup on 14 different times.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown between the French league champions and the French Cup winners after the French winger opened the net early on.
However, the southern French side struck twice late to seize a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout 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 lifted this competition for the twelfth time in the last 13 years.
