230 WATT PSU AND 156 WATT PELT...

[GERRY136]

if i ran a seperate 230 watt psu, would it power a 156 watt pelt if the pelt is the only thing running on it?

[el]

sure. why to you doubt it will run the 156watt pelt?

[Colin]

No.

[GERRY136]

ok what size pc psu would be sufficient?

[jeff_harrison_344]

Of course it will, and will have about......(reaching for calculator).....74 W to spare

Its not that easy as you would assume...your supposed to have like double the power than the peltier requires, right? I can't remember exaclty, so someone is going to have to say how it goes, but I know you can't run the 156w on 156watt PSU.

I think 230w is getting there, but still not enough. If it is twice, then a 300w PSU should be ok, right guys?

id go for 300w just to be sure,

[sfa ok]

Don't psu's have set max amps for each voltage? So that means if I wanted to run a pelt on my 300 watt supply for some reason, I could only have 144 watts of 12v power (12v x 12A). If this is correct, you might be better off making your own that is 15v with lots of watts.

Don't use a computer PSU for a 156 watt tec! You are asking for problems. Get a supply that is up to the task. Check this out http://www.teamdelta.com/products/prod3.htm
$40 for 21 amps not a bad deal and plenty of power. Also has a trimmer so you can adjust the vout.

hey Ken will that $40 power supply handle the 172 watt?

[ken257]

No a 172watt needs 24 volts that is a 12 volt supply ideal for a 156w tec

excellent bro, thanx
