UCSC Genome Browser http://genome.ucsc.edu/cgi-bin/hgPcr?command=start -> PCR: gives only perfect matches with a defined product size cutoff
better use PrimerBlast http://www.ncbi.nlm.nih.gov/tools/primer-blast/ and insert your primer sequences -> gives you all possible pcr products from either genome or cDNA with a defined cutoff (see advanced parameters on that page).

The e-pcr of UCSC works very well. If you want to evaluate possible aspecific amplification products, you can use MFEprimer2 ( http://biocompute.bmi.ac.cn/CZlab/MFEprimer-2.0/).
It will give the product size and sequence if the primers work correctly in the PCR. It does not give BLAST results and I think your question was just verifying PCR amplification.
