Question on tri-sli setup

[gaximodo]

I'll receive 3 9800GTX next week.
Each 9800's gonna take 2 6pin connectors
But I have one problem with my PSU.
It only has 2 8-pin's and 2 6-pin's
in orded to get 2 more 6 pin's ill have to use molex to 6pin adapters

So this is the question: which connector should i use for which card?

which following combanation is the best or they don't make differences?

1: 2 8-pin's go to first card (PCIE 2.0 x16 main card)
2 6-pin's go to second card (PCIE 2.0 x16 SLI)
2 molex-6-pin adatped go to third card (PCIE 1.0 x16 SLI)

2: 8 pin and 6pin go to first card (2.0 main)
8 pin and 6pin go to second (2.0)
molex's third (1.0)

3:8pin 6pin frist
8pin molex second (2.0)
6pin molex third (1.0)

4: 6pin 6pin first
8pin molex and 8 pin molex for second and third

(these 8pin connectors can convert to 6pin's)

thanks in advance!

What kinda of PSU are you using first?
For tri SLI you're gonna need at least 7-800w min because ea. card peaks around 225w, I believe.
if you dont have a big enough psu you can get a GPU PSU that fits in the 5.25 bay.

Thats would seem to be a much better option to get the power to them. I say if you have a rail from the PSU not being used , it could be dedicated to one card on its own and power the first two with the appropriate connectors!
