The Sparkle I use 550 is rated at 32 Amps, and is also powering the rest of the hardware in the computer.
You cannot achieve the full 32A from the 12V rail if you are running the rest of your system from the same PSU.

There is only a single 12V rail in computer PSUs. Multiple wires from the same point do not constitue multiple rails.

To run your 2x80W + 226W at 12V you will need 32A. This is irrespective of how much heat they can transfer. They still consume said electrical wattage.

So, computer PSUs are a good beat to run TECs at the moment.

I'm working on a 700W 12V supply. I'm investigating all the different ways I can realise such large currents. The supply will be water-cooled in itself. When its all done I will post the schematic so everybody can make one.
