Despite heading League One for much of the season, a run of seven defeats in 10 has seen Ronnie Moore's side slip down the table.
Sunday's 3-1 win over Stevenage dragged them back into the top six and Power believes they must start to look up the division again.
"We are all going on about staying in the top six but I don't think it's out of our reach to go up automatically," he told Wirral News.
"If we can be a bit more consistent, put a run together now, it's possible. Who is to say we could not go out and win the next six games? Anything can happen in this division.
"We're going into the next game against Sheffield United with great confidence. If we can get three points from that one we'll be right back in the mix for automatic promotion."
