PSG has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net early on.
However, Marseille fired two times late to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past 13 seasons.
