I just placed an order on the Evga gtx 260 superclocked with 216 shader cores and I was searching around for recommended psu specs.
I found they require 36 amp. This is for the whole system right?
If so I should be good with the 600w psu I have installed (link
It's dual rail both 12v's listed at 20a, but since that's peak I think the real world performance is closer to a total of 36a and not 40a.
The psu does have two 6pin Pci-e connectors.
