Ok - I'd like to upgrade my GPU and was considering:
EVGA GTX 560 Ti SC -- [Requires 500W, 12V, 30A PSU]
Now my 2-year old Antec EarthWatts 650W has three 12V rails, supplying 22A, 22A, and 25A. So obviously I'm out of luck, since I can't make the 30A requirement. (didn't realize 2 years ago that even mid-range cards would require such high currents)
Ok, so now I'm considering:
EVGA GTX 560 SC -- [Requires 450W, 12V, 24A PSU]
Now I'm in business, because I have one rail that supplies 25A. However, how do I know that the 25A rail is supplying the PCIe cable? It doesn't say anywhere on the cable which rail it connects to. Or are all rails connected to any cable through internal circuitry?
Any help would be very much appreciated.
