|That one has four 12 volt rails, avoid it. You should choose a single 12 volt rail so all of the amperage is always available. For example, if your video card requires more amperage than is available on the one 12 volt rail, it may be starved for power while other systems have more available than they need, but if all of your available amperage is always available to whatever system needs it, then that is definitely better. That is a little bit simplistic, but it shows you why we recommend a single 12 volt rail on your power supply. Choosing a power supply with 80% efficiency or better is mainly because in order to achieve 80% or better, they need to use better components and closer tolerances in designing, building, calibrating, and testing, therefore a better, more reliable product. The longer warranty because the manufacturer must then have more confidence in the quality of their product.|
You have to be a little bit crazy to keep you from going insane.
