Google on PSU's?

OMG! Are they THAT STUPID!?!

Higher voltages, like 12V, is always better because higher volts means lower amps. Lower amps means less resistance, better efficiency.

But to make the PSU itself all 12V and then have all of the components regulate the voltage from there is NOT more efficient.

First off, there isn't enough DC current to create enough resistance to have a detrimental affect on efficiency in the first place. There's more to the inefficiency of power supplies than the conversion from AC to a particular DC voltage.

Secondly, there's inefficiency in the regulation of voltage at the component and the more the component has to regulate DC power, the less efficient it's going to be! Do they honestly believe that the regulation on a motherboard is more efficient than regulation within the PSU? I'm sorry, but I'm having a little trouble wrapping my head around a motherboard with enough FET's on it to drop 12V down to 2.5V for my DDR and still be within 80% efficient.

Here's what I think they're thinking: I bet they think that the rails that aren't being used as much as other rails are being "wasted" in the same train of thought as those who think that a 1000W PSU somehow "uses" more power than a 400W when powering the same PC.

And these guys get a NY Times article?! I make a comment on FSP PSU's having too much ripple and I get strung up! At least I know how a power supply works! Am I missing something here?!?! This seems too obvious to me!

I mean... I can see the advantages of having a PSU that just puts out ONE VOLTAGE. But for it to be an effective unit, it would have to have a bunch of 12V rails or one big 12V rail which kind of scares me (70A rail, anyone?) Having higher voltage will mean less amperage all of the way to the location of the component, but unless we change everything to run off of 12V, regulation will still need to be done at the component.
 
I guess if you attach the name Google & claim hugh power savings,
it is very easy to get your trash published in liberal media!

What I would love to know is if anyone associated with that BS has ever even ...

AH, who cares! :p
