Must read article, explains why single rail > dual rail.

That article is very old. Besides, it kind of says that dual is still better, as it is safer.

Questionably safer, and it also shows alot of dual rail PSUs arnt what there power says.
*hugs his single rail 34a PSU*

haha that article was started in 02' lol talking about a 350w psu is the bad boy im sure dual rail has come a long way since then, my PSU has quad 12v rails 15A each 60 amp total power

Well its the 2nd time I have seen such infomation saying the power cant be transfered over from an unused rail, Im yet to see an article declaring dual rails can now transfere power.

That page states infomation from early 2005, its not that old.

Why more than one +12V rail? Electrical isolation for noise and improved voltage regulation. Some devices, usually electromechanical ones having motors, produce noise spikes & voltage fluxuations, these can include pumps, compressors, fans, drives, lights (when turned on & off) and probably TEC’s & Peltiers. By putting these “noisy” devices, that often turn on & off, or at least often change their power (amperage) demands, on a separate rail we isolate them from the MoBo, CPU, Video Card(s) and the other electronic components that are sensitive to noise & sudden changes in voltage. This is a good thing!

Are 2 rails better than 1? Short answer = Yes. It depends on your system as to weather or not dual rails would actually be of any benefit. If yours is a simple system, with no exotic cooling, large disk arrays or flashing lights, then you would probably not benefit from dual rails.

Do I need 2 or more +12V rails? Short answer = No. It depends on your system as to weather or not dual rails would actually be of any benefit. If yours is a complex system, with exotic cooling, large disk arrays or flashing lights, then you would probably benefit from dual rails.

What is the difference between dual rails and just using a splitter? In a dual rail design the PS has two transformer taps and control circuitry for two separate +12V rails. Using a splitter can be very helpful, especially if you split off your “noisy” loads very close to the PS, as this will lessen their effects on your more sensitive components, however the dual rail design would still be much better if you have a lot of “noisy” loads.

quite right
but I would still but a >500 power supply, for headroom, and expansion room later
