, sounds like my concern over the 12V bits is unjustified then. (I'm happy to be wrong
The only concern I have about one big 12V rail is with regards to the devices which connect via 4-pin Molex. I'd need an EE person around to verify but as I remember a lot of consumer devices tended to be "noisy" or make a mess of the electrical, which is why they were segregated from other 12V lines. Possibly that has changed with ATX revision improvements (I don't follow those -- my brain is full!) and vendors are better about it now.
I do remember the whole single rail vs. multiple rail argument, which resulted in a bunch of hullabaloo over "everyone needing multiple rails", then 3-4 years later there's a whole "single rail" movement. I wish people would be consistent.--
