We study the asymptotic behaviour of energies of Ginzburg-Landau type, for maps from $\renk$ into $\rek$, and when the growth exponent $p$ is strictly larger than $k$. We prove a compactness and $\Gamma$-convergence result, with respect to a suitable topology on the Jacobians, seen as $n$-dimensional currents. The limit energy is defined on the class of $n$-integral boundaries $M$, and its density depends locally on the multiplicity of $M$ through a family of optimal profile constants.
