Cable confusion with Quadro 5800 (pic)

[btha]

I'm trying to install a Quadro 5800 to a pretty recent Dell XPS machine (has Core 2 Quad and 8800 GTX right now) but there seems to be some cable mixup. The current 8800 GTX is connected to two of these cables shown in the picture:

However the quadro seems to accept 2x 4 pin connectors (it says on the side that "When connecting both power connectors, both must come from the same rail").

However, these 6 pin connectors do FIT.. it just leaves 2 pins open..

Is it ok to connect? Or no?

Please be sure if you answer, I don't want to fry this very very expensive card lol

Does this help?

It seems you can use a 8 pin connector or 2, 6pin connectors. If I'm getting what the rep is saying.

When you connect them do the lights turn green like he said?

Ahhhhh... Problem solved... The sticker on the side is actually covering the 2nd connector lol.. Plugges 2x3 pins in each and it runs good.
