PCI-E adapter

Hello, I currently have a stock xps 630i desktop, and i am looking at placing a HD 5970 graphics card in the system, but i am worried about the power, it has a 750 watt power supply, but it only has 2 6 pin plugs for the PCI-E power (currently being used by 2 9800gt in SLI). I was wondering if it is possible to use a HDD power cable or something? adapters from 6-8 pin?
I was hoping that i could use a HDD one with adapter or something, so i can still use 1 9800gt as a PPU... Or will i have to buy a new power supply? :(  trying to save money.
Any help would be great.

Cheers (email me on andyandy488@hotmail.com)

your power supply can run 5970 along with 9800gt
but you need one 6 pin and one 8 pin connectors for 5970 and two 6 pin for 9800gt so your psu don't have enough connectors

You do not need an adapter. Like nomad said, the only difference between 6 pin and 8 pin plugs is the number of ground wires. Each has 3 yellow hot wires. The number of ground wires will not affect the amount of power that the plug can provide.

it should work! i hope... haha

any last pointers?

also note that the 9800gt only needs one 6 pin cable... so i use one for the 9800, and then use the molex adapter to make another one, and then convert the last 6pin PCI-E into an 8 pin.

(the only difference between 6 pin adapters and 8 pin is the amount of grounding it has)

ok ... you can go for it, it will get your job done..
