Here we go again with the PSU +12v amperage.
For X1950pro's 450W +12v/30a on a single rail or +12/V20a on dual rail PSUs.
But these are over exaggerated statements from ATi which are recommended with fully loaded systems in mind.
I'm using a PSU with +12V/18a dual rails and it runs without a hitch.
Hell I was using a 450W PSU with +12/15a rail to run the system at one stage.
But to be safe I had to buy a quality PSU.
