Mid-range Dx11 GPUs power reqs

[ShellShock]

I thinking of upgrading to something like a Nvidia 460GTX (from a 9800 GT). The only thing that concerns me is that it requires two power cables. Is this normal for cards in this range? Are there similar spec cards that only use one cable?

Current specs:

GPU: Asus GeForce 9800 GT HybridPower 512MB
PSU: OCZ ModXStream Pro 600w Silent SLI Ready Modular Power Supply
CPU: Intel Core 2 Quad Q8200 LGA775 'Yorkfield' 2.33GHz 4MB-cache
Mobo: Gigabyte GA-EP45-UD3LR Intel P45

Thanks

600W is more than enough for a 460GTX.

The HD6850 only requires a single 6-pin power cable.

I have checked my PSU and it seems to have the necessary power connectors. It has two 8 pin sockets, only one of which is currently used by my GT 98000. I assume I would plug the 460GTX into both of these sockets?

Plenty of power for a 460, 5850 etc with 2x 25A on the 12v rail.
