Re: [H] Question on dual 12V rails

[Hayes Elkins]

Newer ATX12V v2's supply 175W to the SLI connections, as opposed to only 75 
in the old standard. Seasonic's S12 series were the first to address the 
potential problem with newer power hungry SLI cards.

Typically, one +12v rail goes to the motherboard (ATX/SSI, 4pin +12, 8pin 
+12), and the other rail covers everything else...including the standard 
4pin molex, SATA power, and any SLI power connectors. Unfortunately, the 
dual rail system was developed before SLI became a reality, and is a piss 
poor design when SLI is considered.

If a power supply has two 12V rails, how does it split up which goes 
where?  Do the SATA power cables use the same 12V as the PATA power 
cables?
