Use should use both. It will work with one but I'm using both.That's what they are supposed to use.

Are you sure that both molexes on the adapter are supposed to be used?

If i understand correctly the 2 molexs are 1 male & the other is female . you only use the one that suits your PSU connection . you dont need to use them both.

Oops thats right i just checked mine . well in any case 1 molex connector should be sufficent , you dont need the other .
& thats how my SLI setup is running right now .

Kinda makes you wonder why they put two molexes there then LOL! I just put htem both on and we'll see if it fixes my lockup issue.

Oh i see .. well in that case , no i dont think its the molex connectors because i have a similar setup of yours & dont get the issues you mentioned & my 6800GTs are plugged with only 1 molex .

actually you are supposed to hook both molexes up and they should be from seperate unshared lines... Poor power feed for the 6800gt's can cause all sorts of stability problems, I tried 4 PSU's on my rig and found that the 510W PC Power and Cooling SLI is the only one which can handle my GT's (esp. with high overclocks)

I run my GT's at 425 1150

Do you have a source for your info , or you are just guessing from what have you experianced with the PSUs ? because i'm on 1 molex & everything is stable for me .

If the card itself only has one connector, only one PSU line needs to be used, yes? Isn't the adapter just there to allow another component to share the line, in case your PSU doesn't have enough outlets? :confused:

You want to use both. Thats the point of the PCIe cable as far as I know, it takes two molex connections (two +12v wires and two +5v wires) and combines them so the card can get more power.

Yes both must be used from seperate lines as stated by eVGA tech support :)

So eVGA TS told you so .. hmm interesting .
i guess more power will be required once you overclock your 6800GT .. but i assume that for stock speeds it should run stable even with 1 molex .
