The Magpies go into the clash at St James' Park on the back of a derby defeat by Sunderland and an extra-time Capital One Cup loss to Manchester City.
Chelsea, meanwhile, beat City to climb to second in the table and then knocked out Arsenal to make the quarter-finals of the League Cup.
Newcastle boss Pardew said: "I think we have got an even chance against Chelsea, I genuinely do - as well as they are playing because I think my team is playing well.
"But you need those breaks and things to go your way and the first goal will be important in this fixture.
"To beat one of the top teams - and let's be honest, Chelsea are one of those, and we have got Spurs after that, who are in great form as well - you need to be at your very best."
Last weekend's victory was Sunderland's first of the season and gave Gus Poyet's side a much-needed lift.
But the Uruguayan wants his players to forget about it ahead of Saturday's trip to Hull.
Poyet said: "Now I think it's going to be - it should be - a little bit easier after this win.
"The key now is to forget. Newcastle is gone, finished. Now it is all about Hull City.
"The idea is to keep winning. We need to win football matches and without any doubt the feeling you have got inside is totally different now to last week."
West Brom will be looking for a first win in four games when they face bottom side Crystal Palace.
Scoring has been the Baggies' main problem, with their strikers especially goal shy so far this season.
Boss Steve Clarke said: "We just work every week in training. There is always a group who will stay behind and do extra shooting.
"We do shooting within the training sessions, working on little practices to encourage bright, quick play in and around the box and getting shots away, and being in the right position.
"I can promise you they are scoring a lot of goals in training and eventually that will transfer to the pitch."
Caretaker boss Keith Millen will again take charge of Palace while the Eagles continue their search for a permanent successor to Ian Holloway.
That will not be Millen, who is not putting his name forward despite Palace impressing in his first match against Arsenal last weekend.
He said: ''I have worked closely with the players now for a long time and I enjoy it, but I think someone from the outside coming in will give us a little bit more of a lift.
''I loved it, I really did and I have missed it, but I enjoy coaching the players as well. To be in charge of Crystal Palace in the Premier League was a dream come true."
