Wigan piled on the early pressure as they went in search of a lead, with Manchester United loanee Powell forcing Sergey Ryzhikov into a good save in the ninth minute of the game.
Wigan looked to grab an equaliser before half time with Ben Watson testing Ryzhikov again, but the goalkeeper did well to get himself behind the ball.
With the clock ticking towards the break Rubin thought they had done enough to get into their dressing room unscathed, but Powell had other ideas as he took hold of Watson's pass before firing into the net to leave the score at 1-1 going into the break.
Both sides pushed for a winner in the latter stages of the second half, but neither could fashion a telling chance.
Marc-Antoine Fortune perhaps had the best opportunity, though Ryzhikov was equal to his effort in the dying minutes as the game ended 1-1.
