single rails provide much cleaner power and are able to supply the extra amperage
You keep saying this. Can you provide some support for this statement please?
okay, I had a brand-new 700watt atx, that had 5 12v rails, which totally fried just trying to run a Saturn for 5 lousy minutes. Why?...each of the two pci feeds had a 150 watt rating, and the boards draw very close to that amount. It fried. I'm trying to save you from my mistakes....
Why would anyone want a multirail psu anyway? one rail overloads....you're done.
with a single 12v rail, no single pci feed can overload the psu...nor hamper the hashrate from limiting the current flow due to overdraw....period!
Hope that helps..
*Some may forget, but I'm an energy researcher, and recently consultant to a large energy corporation in development of fuel gasification technologies, more specifically in the development of more efficient systems using resonant energies through the application of harnessing the bounce of signal between a HV coil, and a PWM, as well as the enhancement of combustion through the use of adding Direct Injection, plasma ignition, and Hydroxy gasses made through the harnessing of the coil HV signal bounce, and shunted to a 143 plate cell where it is produced, and then metered into the Gaseous injection system, mixed with the vapors from whatever your fuel is in the gassifier...
enough on that...
but I can't stress enough how the actual current reaching any electronic(especially digital)device is critical to it's performance.
