How much power is needed for two 9800GTXs in SLI?

Q: I have a 650W power supply and I'm wondering If this is enough wattage to run two GeForce 9800GTXs in SLI?

A: Here is a good link to get an idea of a power supply that will work/be needed with 2 9800 GTX cards http://www.slizone.com/object/slizone_build_psu.html At this link you will see a configuration for Dual 9800 GTX cards and a drop down list of certified/tested power supplies that are known to work with this configuration. This site also has some other nice things to read up on about Nvidia and SLI configurations. According to the link 650 watts might be enough, but it really depends on the model/specs (amps) of the power supply. I hope this helps.
