PSG has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the net early on.
However, Marseille fired two times in the closing moments to take a surprise advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 years.
