Where are you coming up with these crazy numbers, bub? "His" (my) X1900XT is not overclocked any at all, to begin with.
According to the ATI Tool screen capture, the default clocks are 500 core and 600 mem. The current operating core and mem clocks are reported as 621 and 720, respectively. The 'find max core and mem' buttons are greyed out (i.e. they have been activated), leaving only the abort and default reset buttons available. Based on my knowledge of ATI Tool, it appears that you are using the 'find max core and mem' overclocking feature of ATI Tool and the actual clocks have been increased to 621 and 720. Correct me if I'm wrong.
That screenshot was taken with an X2 4400 at stock speed and vcore, along with the X1900XT at stock speed and voltages, so 27A would be about right, since the processor itself would be using 8-9A of 12v power, along with around 2A total for the HD and fans, that would leave ~16A for the video card, which seems just about right, from what I've heard.
10A MAX of +12V current for X1900XTX, as
I've already established (9.75A measured).
Can't get even 300W from this setup factoring all components at 100% MAX load, which is practically impossible. At any rate, ATI Tool can't accurately calculate or extrapolate total system power or +12V current without being able to measure the voltage drop (delta) to some reasonable degree of accuracy (or using induction clamps). I don't know what ATI Tool is measuring, but it ain't +12V current. It might be guesstimating based on some set of assumptions...
