PSG has now won the prestigious cup on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the net in the opening stages.
However, the southern French side fired twice late to seize a shock lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the last 13 seasons.
