9500gt to upgraded 9800gt?

Hello,
I have a 9500gt 512mb ddr2 in my pc right now, but i want to updrade to a 9800gt 1gb ddr3. Im not sure what im suppose to do with the connecting part. The 9800 comes with a 6 pin connector. My question is, Can i take the white connections from both my floppy disk and my dvd to plug into the connector then into the graphics card? I have two dvd trays and a floppy disk tray that i dont use. Thank you
Ps i have a okia atx 400w power supply
