Just to be clear, you don't need an 850watt power supply to run that one card, a 650-700 watt power supply would work as well. Now if you're running two of those cards, than yeah an 850 would be good.
Also, if you don't have enough of the PCI Express 6 pin power connectors, the new graphics cards will come with adapters to convert molex connections (2) into a 6 pin PCI-Express (1).
So, it's also not necessary to replace your power supply if you run into this specific issue.
You'll need a 6 pin and an 8 pin. (A 6+2 PCI-E cable can be used as either a 6 or 8 pin.)
nVidia has a list of PSUs that they certify for various multi-card setups:
Build an SLI PC - Certified SLI-Ready Power Supplies
If a good 950W PSU is adequate for two 580 cards in a system, then 650W ought to be adequate for one card. (Gigabyte recommends a minimum of 750W, but a good 650W PSU may offer more +12V current than a poor 750W one.)
