It's ill-advise to use a power adapter, even though some have been successful in using adapters. 6-pin sends less wattage than an 8-pin, and an adapter doesn't help this. It has been said that the extra 2 pins are merely grounding cables, but in some way, the 8-pin and 6+2 pin cables seem to send more power.

The GX2 needs some good solid power, and I would expect future nVidia flagships to have the same, if not more, power requirements and the use of 8-pin PCI-E connectors.

I first thought about just getting an adapter, but I took a long look at my PSU and decided to upgrade to one with 2 6+2-pin PCI-E connectors. This will allow me to have video cards that use either 2 6-pin, one 6-pin + one 8-pin, or 2 8-pin. I also made the decision to find a PSU with a single huge rail with at least 45a, and found one with a single 12v rail at 52a, currently in my sig rig.

If you are spending $590 for a GX2, why not spend some more on an upgraded/updated PSU to match it?

Agreed, I wouldn't cheap out with an adapter. Get a proper PSU. You've already spent all this money on this bad ass card, don't choke it.

I was fortunate in getting a PSU that has the right connectors as standard for the GX2. Not only that but it has more than enough power for Quad SLI. 70Amp single rail does the business.

do not use an adapter it says right on the site it will not work so be sure to get the right PSU if you dont want to kill the card.

The one I bought from Gigabyte came with an adapter and I'm using it now without issue. One thing to note is that the 8-pin connector on the 9800GX2 is very picky, not all 8-pin power connectors will fit right.

It's not about the wattage...it's about the current (amps) that a PSU puts out that determines whether or not it is sufficient.
