3dcool 156w Peltier runs on only 12v?

[JML]

That's what they claim at least. So does this mean I can use a normal computer PSU?! I could get a decent computer PSU pretty cheap.

You'll need to push quite a bit of amps to get its full effects

[eradda02]

where did you see only 12??? most are 24

[Colin]

The 156 watt TEC has a VMax of 16.9 volts and will run at reduced output on 12 volts. It needs a solid 11 amps. You can lower the voltage but don't reduce the current.

yep, just make sure you have the amperage supplied to it and you are ok.

[AMDgeek]

unless you have a monster power suply the 12 volt suply on most can only suply 3.3amps and the pelt will draw more than the power suply can handle and coook the power suply

A 156 watt TEC cooked the mighty Enermax 651 in my box.

Check your label again AMD most PSU are lot higher than that
more like 13.3A, I think off the top of my head mine is about 16A
My calculations says you will require 13A for the pelt alone.

http://www.sparklepower.com/products.htm the 400 watt power suply has a 12 A max. I re read lable on my 300 watt and it has 10A max. so I mis read, but it is still is to low to power the pelt and your comp at the same time

The power supply I would use would be dedicated to the 156w pelt alone. I need one that can put out a lot of amps at 12v to handle the load, any suggestions?

500w psu = $25

I checked out this supply, the best it can output is 12v@12amps. No better than a regular AT or ATX supply.

[bdf24]

I think my Enermax puts out a 15amps on the 12v line. That should be plenty to power a tec. Hell I run my 85w and system on the same PSU, 431w enermax. But I dont think I would do it with a 156w tec. I think that would be to much for it.

you can get 24V from a standard PSU
as voltage is potential difference....
a PSU has a +12 V and a -12V
is it just me or does anyone else also see 24V

Yeah you could get 24V but the -12V supply is only rated around 1 amp. So you connect a 156W pelt to it and you get a nice blue flash and the smell of burning, Nice !

[most deaf]

most of them run at 12 volts so u can use it easly with u r pus, the problem is the amps, if u have anything else on the same psu it will kill it
