Need help with powering my 172w Peltier! (TEC)

.. the topic says it all..

172watts is the heat dissapation.. here are the actual energy specs


221watts

11.7amps

24vdc (only need 17vdc to 18vdc as any higher doesn't result in better cooling..)

so.. i've been going over and over how to supply power to this.. a second 400w power supply? or what? i don't want to spend more then 40 bucks for any item unless it's another ATX power supply..
