it is possible to calculate the angle depending to the width and
height of the box, but it seems to be easier to insert this
angles by hand:

\documentclass[12pt]{article}
\usepackage{pst-node}
\begin{document}
\begin{pspicture}(8,4)
  \rput(0,0){\rnode{node1}{\psframebox{$G_1*G_2$}}}
  \rput(3,-2){\rnode{node2}{\psframebox{$H$}}}
\end{pspicture}
\ncdiag[angleA=-20,angleB=137,arm=0]{node1}{node2}
\end{document}
