PSG has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful 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 sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup holders after the French winger opened the net in the opening stages.
Yet, Marseille fired twice late to take a surprise advantage. First, the English forward 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 grabbed a vital equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
