The Parisian club has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup winners after the French winger found the net early on.
However, Marseille fired two times late to seize a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the 12th time in the last 13 years.
