The limiting factor on the resistor is power dissipation. Nothing to do with voltage rating.

If you had 750 volts across a 2.7K resistor, it would be pumping out over 200W!
Old TV Nut had it right, you hit the 3W mark at 90 volts so there better be much less than that across the resistor. |
It's not more concerned 750 "across" the resistor itself, but more the being at that potential as a whole, and the possibility of there to be a breech of the outer layer if the voltage rating is to high.
