There is a chance that you could use a DC/DC converter to switch the DC up to about 100VDC. If the power supply is a simple off line switch converter, it simply rectifies the line to DC and uses that. Just a long shot. Last time I took a PC power supply apart, that is how they worked (AT supplies). A 12V to 100V DC/DC converter ought to be much simpler to build.
