I hear people talking about power supply rails all the time. I already know about wattages, but not about power supply rails and there is not too much information out there. Can i get a general explanation?
Multiple rail configs let you fine tune OCP better by isolating parts. Single rail power supplies are hassle free, letting you put all of your parts in and not worry about power as long as your total wattage is high enough. I a single +12 V rail, and I believe my opinion lies with the majority.
