- The 350W PSUs you cite do not provide in any way 350W of power on a single rail. If you want 12V/350W (for example) you'll pay a lot more.
- In my previous post i carefully chosed the 'power' term and not 'voltage'. If you want, say, 100W of cooling, with 50% of inefficiencies (not far away from reality) you must provide 150W of power. Even when using a 200W rated device.
- if you happen to use one of those devices at 10% of its rated power, how does it behave ? Is it any better than an 'usual' pelt ?

The strong point of this new device is thermal density. It's clearly beyond the best peltiers i've seen or heard of.
Another strong point seems to be efficiency.
But i'll take the example of helium phase change cooling: it's possible, works wonders, but aint it a tad expensive ?
Given the specs of that technology, i fear the price would make it useable by army, aerospace, labs but not PC enthusiasts...
