Value?, pick a number. I recently ordered 1500 Ohm, 7W wirewound resistors for an 80V supply. Just remember Ohm's law - you can determine the power rating from the voltage and chosen resistor value (P = V*V/R) - the lower the value the quicker it will discharge, but the beefier the resistor needs to be, and the more energy you throw away.
