here is my situation

I and the cube owning community want to put radeon 9800's in our beloved cubes some nice fellow has even found a card that fit's (flashed pc 9800se)
and runs at 9800 pro speeds the only problem is how to power the card.

the card has a connector on the corner like the retail mac edition obiously this card has no adc so the 28 volt connector on the agp slot is not being used and can be intersepted at annother easy point in the cube and this wire has 100 watts behind it it compleatly bypasses the DC-DC board in the cube (the most delicate part in the cube that splits the incomming 28 volts up into multiple voltages one cannot use this board as it would fry as it can oly handle 100 watts)
the power brick can supply 200watts 100 for the cube and 100 for the adc display.

now you have the problem and the backround i need to know the best smallest way to convert a 28 volt line into a molex connector for the 9800 and maby a few extra to take the load from the dc-dc board.

would annother type of dc-dc board be required if so how could i get/make one?

or could you use resistors?

(yes you can use annother external power supply but it is inelegent and you have a noisy power supply to deal with)
