PSG has now claimed the season-opening trophy on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the match between the French league winners and the French Cup winners after the French winger found the net in the opening stages.
However, Marseille struck two times in the closing moments to take a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
