    I haven't been keeping up on the latest in computer trends and I don't know shit about electricity, so I have no idea about this. I need to upgrade my power supply so that I have sufficient amperage on the 12v rail to support my new video card, 26 amps to be exact. So I was shopping power supplies and noticed that a lot of newer ones have 2 12v rails. I am just curious if both these 12v rails are the same as having 1 12v rail? Or do they work completely separate of each other?

    TIA

    v * a = watts

    ohms law

    a second 12v rail is usually only needed for 2 video cards (SLI) so no you don't need it, what you need is a quality ps with enough wattage and stable output to support all your devices.
