I found out your card is green version which doesn't require, and doesn't have 6pin.
Therefor power is taken from the PCIE slots only.
Because your PSU doesn't provide sufficient power to the PCIE, it won't work.
You've been getting this same answer many times.
So either buy a PSU in the range Mr Grim has given you earlier,
or buy two new graphics cards that do have 6 pins.
The 9800 gt cards are actually 8800's with a new sticker on them.
About SLI I don't know enough to give an educated answer.
Mr Grim?
