PSG has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 champions and the French Cup holders after the French winger opened the net in the opening stages.
Yet, Marseille struck twice late to seize a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched 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, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
