Jardim's men visit the Parc des Princes on Wednesday having held them to a goalless draw in Ligue 1 on Sunday.
That result saw a profligate PSG miss the chance to go top of the table as they failed to capitalise on league leaders Lyon's 2-1 loss at Lille a day earlier.
However, Jardim does not believe the game will necessarily be decisive in determining the destination of the French football's oldest trophy.
"This match against Paris is not an early final," Jardim said. "There are always surprises in the Coupe de France."
Asked about the strain of playing three games in a week, Jardim - whose side beat Arsenal 3-1 in the UEFA Champions League last week - added: "We must adapt to this situation to manage the workforce reduced by injuries and suspensions."
Laurent Blanc's PSG also head into the game without a host of key players.
"We lacked the finishing touch, we didn't put the ball away and we're disappointed, but we have to stay positive," Matuidi said.
"We carved out a lot of good opportunities to score, and conceded very few, which means we were well organised.
"Wednesday's match will be different, we will have the supporters behind us, but we need to work on our recovery now. The better team physically, we almost certainly win the quarter-final."
