9800gtx+ power plugs

[Surrealistic]

hi, im running a single 9800gtx right now and am about to be adding a second one for sli goodness, "problem" is, my power supply only has 2 6 pin plugs, but has 2 8 pin plugs, my question is, can i use the 8 pin plugs in the 6 pin sockets (the 9800gtx has 2 6 pin sockets) or is there a 8 pin to 6 pin adapter, im having a hell of a time trying to find one if there is

*edit* i know there are molex to 6 pin adapters, but im going for a cleaner look, and getting 8pin to 6pin will look much cleaner in my case :/

If it's a 2+6 pin, it will work no problem.
I'm using 2+6 pins to power one of the 285s in my secondary rig. (Corsair HX1000w PSU)

Some video cards have 6 Pin PCI Express power connectors and others have 8 Pin PCI Express power connectors. Many power supplies come with a 6+2 PCI Express power cable which is compatible with both kinds of video cards. The 6+2 PCI Express power cable is made up of two pieces: a 6 pin piece, and a 2 pin piece. If you put the two pieces together then you have a full 8 pin PCI Express power cable. But if you split the connector into two parts then you can plug the 6 pin part into the older 6 pin PCI Express connector and leave the 2 pin part unplugged. That way, your power supply only needs to have one 6+2 cable to be compatible with both 6 pin and 8 pin PCI Express connectors.
