PSG has now claimed the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable win in the match between the French league winners and the French Cup winners after Ousmane Dembele opened the net early on.
However, Marseille fired twice late to seize a surprise advantage. Initially, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
