interesting advertising at least...

This article is published by a PSU manufacturer.

Just sounds like a lot of PC Power propaganda to me.

At least the part about efficiency seems plausible...though this falls by the wayside when you start saying that this holds true 100% of the time.

My .. apparently .. high quality PSU had a turbo mode to combine all 12V power rails into a single power rail.

Potentially, you can waste alot of your power allocation on multiple rails ....
Although initially the argument was that you can minimise noise or similar.

We have a similar issue with some big transformers ...

Power Supply Authourity want to give us 2x 1000KVA + 1x 500KVA trannies (@230VAC) .. but mech services alone want 1800A .. means you have to split up the loads & allow much high safety margin for startups... nyah .. wasted capacity!

We just want one big 2000KVA tranny

I've previously chalked up the "multiple 12V rails is good" excuse to the same list as "Crumple Zones improve safety" list. It saves $$$ for the manufacturer rather than provides any real benefit to the customer.
I've always been of the .. "just add some decent voltage regulation circuit to the single rail" camp .. but of course, there is always some idiot ready to shout louder.

I can't elaborate any on the technical merits of it, but I can say that as mciahel alluded to, anytime a manufacturer of a certain item hypes its own product, that kind of advertising is invalid and essentially commits a breach in terms of an intentional fallacy (i.e., the author of a book telling you what everything means). If this were presented by a tech expert at Consumer Reports, this would have been completely different in presentation and in endorsing a certain product.
