I can drive a Peltier with a switching power supply like that from a PC.
An ATX power supply Volt output matches the demand by the peltier unit.
But some the Peltier only wants 12 VDC at 6.5 amps
The ATX I have in my hand has the following listing for Max output:
+5 VDC at 5 amps 200 watts
+3.3 VDC at 28 amps 200 watts
+12 VDC at 45 amps 540 Watts
Then there are some other call out I don't understand:
-12 VDC at 0.6Amps 7.2 Watts
+5VSB at 2.5 amps 12.5 Watts
Will the excess amps available 28A harm the peltier or will it simply not draw that?
