PSG has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net early on.
However, Marseille fired two times late to seize a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
