The Parisian club has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the showdown between the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille struck two times in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a convincing shootout victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
