I need some PSU suggestions. I am planning on buying the following i7 rig next week and I am going to be using my 9600GT until the end of August. After that I plan on buying either a GTX 275 or a GTX 285 and using the 9600 GT as a physics card (Possibly add a second GTX card in the future for SLI). I currently own an EarthWatts 430 but I don't want to risk my rig with it. Will my current PSU be fine until I get a new GPU?
