Long ago Intel required dual 12v rails for power supplies in systems based on that unmitigated disaster called "Prescott", the thought being that a dedicated rail for CPU and another for peripherals would ensure clean power and push manufacturers to beef up wattage.
Forward to today where we now have GPUs that surpass power draw of most CPUs and how any one component can surge in draw, Intel has backpeddled and now sanctions (as per their online builders spec guide) the use of massive 12v single rail power supplies because of how dynamic these draws can be. What good is a dedicated 20A 12V rail when a GPU can have a peak of 25-30A? > Date: Thu, 8 May 2008 20:26:18 -0700 > From: [EMAIL PROTECTED] > To: hardware@hardwaregroup.com > Subject: Re: [H] PC Power & Cooling S75QB 750W EPS12V Power Supply $149 free > shipping > > Is a single 60A 12V rail better than multiple 12V > rails totaling ~60A?
