The MSSM distinguishes itself from other GUT's by a successful prediction ofmany unrelated phenomena with a minimum number of parameters. Among them: a)Unification of the couplings constants; b)Unification of the masses; c) Protondecay; d) Electroweak symmetry breaking. A combined fit of the free parametersin the MSSM to these low energy constraints shows that the MSSM model cansatisfy these constraints simultaneously. From the fitted parameters the massesof the as yet unobserved superpartners of the SM particles are predicted. The2nd order QCD coupling constant is required to be between 0.108 and 0.132. Itis shown that a top mass of $174\pm16$ GeV, as suggested recently by the CDFCollaboration, constrains the mixing angle between the Higgs doublets in theMSSM to: $1.2<\tb<5.5$ at the 90% C.L.. The most probable value corresponds to$\tb = 1.56$, which leads to a stop mass below the top mass. In this case thestop production in $p\bar{p}$ collisions would contribute to the top signature.This could be an explanation for the large effective $t\bar{t}$ cross sectionobserved by CDF.Comment: latex + eps fig IEKP-KA/94-0
