If you're so inclinded, you can get power supplies, at least for 
servers, that run on 48V DC or with some models, about 200V DC.  Of 
course, if you're handy with a soldering iron, you may be able to modify 
an AC power supply to run on high voltage DC.  Come to think of it, an 
AC supply should already run fine on a DC voltage of at least 150V, as 
the AC is just rectified, before being passed to the power oscillator.
