Hughes' side, who have taken only one point from three top-flight fixtures so far, travel along the South Coast to face Brighton on Tuesday night.
"I think it's really important, we want a cup run, we want the excitement of a cup run if we can," said Hughes.
"I've always been of the view that cup runs don't hamper your league form, they enhance it. Because confidence comes from progressing into the latter rounds.
"If we can do that I think it will help our league form and our confidence going into the Premier League games. So our intention is to get through the tie if we can."
