Not the best solution...but... (Score 1)

Not the smartest way to do it, since you can explode a power supply. I had a line conditioner (Tripplite) that I was able to tweak a small rheostat and jack up it's output voltage. So the conditioner output more than the standard 120v(I think I ran it at 123v). This in turn made the transformer in the power supply output the 5v I needed. Although it worked for me this is dangerous, try at your own risk.
