Can I run this 226W TEC on a Thermaltake Purepower 420 PSU ?
From the TEC spec sheet:
I don't understand how the same TEC requires 25A, 18A, and 40A all in the same paragraph.
Do they recommend the 25A PSU because of inefficiency? The spec sheet for the Thermaltake PSU claims 18A at 12V, is that going to be sufficient assuming the TEC is the only load?
I'm very much hoping I can use this PSU because it's the only spare I have laying around. Naturally I'd prefer to save a buck and use what I have. Can I get away with that here, or do I need to buy the PSU they recommend?

From the TEC spec sheet:
Power Supply Requirements
* Auxiliary power supply :
o The TEC module is provided with "bare wires" to facilitate installation with screw type terminals.
o We recommend the "Meanwell S320-12" power supply, rated for 25A at 12 Volts.
* While it is possible to connect the MCW5002 to the computer power-supply, users should be aware that only high-end power-supplies can accommodate the Peltier module 18amps current draw (at 12 volts). Accordingly, users should verify that their power supply features at least a 40 Amps ratings for the +12 volts rail.
