And even if the label says its 18A per rail they are rarely set at that, it's usually set at least a few amps above that (but that is not a relevant topic to this thread). On top of that a graphics card will draw up to 75W from the PCI-E slot which is on a different rail.
Hmmm well as I said i'm not sure on this one. According to nvidia forums, it specifies it needs a 24amp rail on a 450W power supply.
And according to the picture of the actual power supply he has it says it can only output 18. Since he is having issues, and the 9800 is reccomended by the people who produce it to have a 24amp rail on it, that would be the first place I would look.
I do agree that 288 doesnt sound right but I'm just going by whats on the box. They know their products better than any of us, so I'd atleast try out a different PSU if you can get your hands on one. (if your pc is BSODing or locking up or shutting down, not if your getting driver errors)
