HITC Sport understands that the 21-year-old is poised to join Gary Caldwell's rebuilding project at the DW Stadium.
The highly-rated midfielder is already a seasoned performer in the Football League despite being just 21 years of age.
He has been part of Tranmere’s first-team set-up since 2011 and has gone on to make over 120- appearances for the club.
Power has developed year on year, and the 2014/15 campaign was his most productive to date – despite it being a forgettable one for his current employers.
His goal-scoring exploits, which saw him net on 13 occasions in all competitions, have not gone unnoticed and he could now find himself on the move.
Wigan are looking for reinforcements capable of helping them to bounce back into the Championship at the first time of asking.
They see Power, as a man who impressed in League One before dropping into the fourth tier with Rovers, as a useful addition to their ranks.
Tranmere will be understandably disappointed to see a home-grown talent leave, but their relegation out of the Football League has left them open to raids from afar.
