Re: re: 5v @45A. John, that was a typo. It's since been cleared up. The on-board regulator needs to provide up to 45A of current. The on-board regulator on most boards draws from the +5V rail on the power supply, I think that's where the confusion came from. Watts needed are 45A x CPU volts (plus a little loss) so watts needed are 45 x 1.65 max (75) which is 15A from the +5 rail of the power supply. Some of the newer AMD boards (such as Asus's A7M266-D) and almost all P4 boards take their power from the +12V rail of the power supply, where it's a lot easier to deliver that kind of power. P4, of course, had to go to the +12V rail for power, since the faster .18 P4's used 95W. Regards, Dan
