The "What power supply can be used for my TEC" thread

I have noticed the rather large volume of threads asking if a certain power supply can be used. This is an attempt at addressing that barrage of questions.

• Can I just plug my TEC into the computer PSU?
  In general, this is not recommended, except for the smallest TECs (80W). The best way to determine if it will work or not is to look at the power supply's rating on the 12V rail, and then check how much current your TEC will draw (look at Imax here). A quick approximation can be made by taking the Imax listed there and calculate as follows:
  
  I = 12V/Vmax * Imax
  
  This will not be 100% accurate, as TECs are non-linear, but it will give you a ballpark figure. If you're using your computer on the same supply, ensure that you have substantially more current available than the TEC will be drawing.
  
• The best method is still to get a dedicated power supply.
  The Meanwell supplies are fairly popular, and can be purchased at various online vendors ( www.cooltechnica.com www.dangerden.com to name a couple). Ebay is a good spot to find relatively cheap supplies as well. When doing this, ensure that the current the supply can source is higher than what the TEC will draw.
  
• Can I get 24V out of a standard ATX/AT power supply to run my 24V TEC?
  24V can be gotten from an ATX or AT supply, but it will probably not work well for a TEC. This is because the supply does have -12V and -5V lines, but they are not rated to handle very much current, so using them to power a TEC would probably burn it out.
  However, here are some articles which may be of interest:
  http://www.procooling.com/articles/h...ween_psu_s.php
  and
  http://www.procooling.com/articles/h..._s_as_one_.php

That's all I can think of at the moment. Feel free to add more ;).

One thing i would add to this guide is that when selecting a PSU keep in mind that most PSU's run best at 75% load so if you know you need 24A look for around 32 -33A on the +12 ECT...

Antec Trucontrol 550watt can power 2 swiftech mcw50-t's and a full system:)

Hi just ripped this psu out of an old comp.
Prodmedia
Model: SPS-250-15XE
Ac imput: AC115v/230v 5/3a 50/60hz
Dc Output: 12a/18a/5a/0.5a/0.5a/0.15a/92w max

Could i use this to power a 172w pelt or since its 92w max do i have to only use 80w pelt on nb.

you can run that 172W at 12 volt, but it will only be about 90W... but still better than an 80W :)

You'd probably be okay with a 172W TEC with that particular setup.

I use an Enermax to power my 226watt and my 80watt pelt.

This one.

http://www.newegg.com/app/ViewProduc...=BROWSE&depa=0

Its 12v is @ 33amps

This Enermax Bad Boys kick massive a$$. love them!

I was told that using an ATX PSU only for pelts didn´t work properly, because the 5v rail and the 3.3 rail, didn´t have any load and the PSU ended up giving less amps for the 12v. What would be the best option for a 172W and a 226W pelts?? The meanwell of 25A won´t be powerfull enough right??

Not by itself. If you get one that can put out 33A or or more, you should be good. You can use an ATX suppy if you put some kind of load on the 5V rail (say a 1 Ohm resistor, so that it draws 5A).

i can buy a psu for a tec... seems pretty good
Regulated 13.8V power supply 25A
would this be good for a 226 watt tec?

*link to specs*

for sale @ dutch store for € 89,95

Yep, I use a 13.8V 23A supply for my TEC, it works fine.

WOW!!! I want that 40A PSU in that link.

Heres a link to one and adjustable voltage.
http://www.testequipmentandtools.com...VDC__40A_.html

Heres I think is another one a little cheaper.

I want to get the Swiftech Chiller but with two 226W TECS take alot of juice. You think this PSU could handle it?

Would a Forton 530 or TTGI520SS (18A 12V) be enough to power a maze4-1 with an 80 watt TEC along with my system?
I have 2 optical drives now and plan on adding 2 more HDDs to my current one during the summer. Would it run or no?

EDIT:
DAMN that Enermax looks awesome. That would be fine right?

yeah the power supply would be ok can handle that current.
you have a big power supply 400 to 500w should handle that ok
i know from my power point i can draw 15A at 240V so max of 3600W off this one power point. the only thing that might trip the mains is if your running you chillier and you turn it off. and then turn it back on the start surge current might trip the mains, just wait a few minutes and you should be ok.

I'm looking for a power supply that can do 60Amps at 15 volts, any suggestions?

Not going to be easy to find, nor inexpensive, 60 amps @ 15v, 15v is going to be the difficult part, (unless you go custom) most DC supplies are designed for 13.8v, some will run 14.5 or so, but you pay even more. do you have a particular price in mind or is this price doesn't matter?

see this thread for a little reading material..

http://xtremesystems.org/forums/show...ghlight=xforce

Well, I did find one... It's a meanwell

http://www.meanwell.com/product/psp-1000/default.htm

However, I'm looking to see if there are any others out there.

The reason I want one PSU is for the 15v. I want 15v so I don't have to sacrafice performance at 12v. I mean, I would just get 2 'regular' Meanwells and hook them up to each TEC, but if I did that I'd lose some watts and I don't want that. I just want a PSU that can do 15v at 30-35 amps, or a PSU that can do 15v at 60amps.

Here are the TEC's

For the CPU:
Model CP1-12726
50mm x 50mm x 3.64mm
245 - 320 Watts of cooling power
Operates from 0-15.4 volts DC and 0-26 amps

For the GPU:
Imax = 24 Amps
Qmax = 226.1 Watts
Vmax = 15.2 Volts
Delta Tmax = >67 (C)
Size = 50mm X 50mm X 3.10mm

I doubt you will find anything more suitable then the meanwell...

I didn't think so, but it's worth asking. Thanks anyways.

Currently I'm using an Antec Truepower 550W to power my rig. Would the PSU be able to handle an additional 172W Pelt?

i dont think so. that tec draws a lot of power :-)

I'm going to be using a pcp&c 510 deluxe with factory modded and fully adjustable rails to power the following rig

fx-55/vapochill LS/x800xt-pe or 6800U (voltmodded)/1GB pc3700/dfi mobo, 80GB raptor/pci cards, etc, etc

Can I add a 172 watt pelt to it as well as a northbridge TEC? I would think so since I saw a video where someone plugged a hard drive into every single molex connector available (something like 10) and the line didnt drop .01 under load, but I know tec's are a lot different than hd's...

think I'll be ok?

http://cgi.ebay.com/ws/eBayISAPI.dll...845385194&rd=1

guys do you think that a powerful 300W Fortron can power 2 of these?

it says : Operates from 0-15 volts DC and 0-8 amps

fortron gives 15amps at 12v. so i wonder if there ll be a problem about the high amperage on the tecs..

thanks

little late: did u get the chiller? to be honest: i hope not
Try finding a decent waterchiller on phase change
I bought one for 150 euro (about 0 degrees C 355 watt or -10 graden 222 watt capacity) which is plug & play :)

pal, i think that these are pretty weak pelts with low amp needs. so i thought 15a

do you think that there is a chance of explosion in the Fortron if i get to give it a try?

Your talking about 190 watts and 16 amps total...
Lower V is usually is not a problem on a pelt, but lower amps aint a good plan.
(plz some one correct me if i'm wrong :P i'm not the expert on it but i know certain basics :P)
The difference is low, so well, its not gona explode but the tecs might not work optimal or dont workt very well at all

am building a tec setup and i have a 13.8v 30 amps power supply, now what would be the most powerfull 40 x40 tec i could use ?

probably any 40x40 tec u want... 30amp ps is a lot :)
the problem is the low V from what i can c....
havent found any 40x40 that do sub 14v
50x50 226w would work excellent on that ps


btw 3x0
from the tec faq in this forum:

-Dangers to be Avoided (stuff you don’t wanna do) –

The biggest danger is attaching a TEC that is underpowered; many have cooked their brand new processors doing this. :cry Of course, this is easily avoided; just don’t attach a TEC will less cooling power than your CPU generates.

i have been looking around for a high watt tec who would run well @ 13.8v but they all seem to need 24 v

i have a 227W tec that runs 15v with 15a :D
but its 50x50mm... still great tec :) can run it on my fortron psu with 12v@15v :)

For those of you with a bit of experiance building circuits, here is a link on how to build one for cheap http://www.overclockers.com/tips1054/

maybe that article addressed this, but why would a powersupply for thermoelectics even need filtering? why not isolate it from the mains and then full wave rectify it?

Are there any PSU's that are capable of running two of these without making me go broke?

Uhm...let me see....the amount of electricity consumed is based on the TEC, not the PSU....you would need a sufficiently large PSU to run it...but the PSU would only consume enough to power the TEC...see how this works?

So basically, the TECs would make you go broke if you ran two of those, if you need THAT much cooling power...go with phase change water cooling...it's far cheaper.

Hey guys, i have an idee for a TEC supply. Most cars today use alot of Ampére. My 1100cc even has a 40A 12V battery. What u can do is use one of those, or maybe u can use a car battery charger. My dad has one and it can output more then 100A @ 12V i think.
For benching that is. I don't see someone use that kind if supply in their cases :D

I have this as a second PSU:

---

Does this mean that if I mod this PSU I can get the 12v line up to 15.6v without a problem? Could I power the TEC @ 15.6v with this single PSU?

Hello. :)

I have a 170W(50mm) TEC with an operating requirement of 0-15V and 0-15Amps. I am planning to use a spare ATX PSU with a 12V rating of 15Amps. But since SHROOMER said that a PSU runs best at 75% load, and assuming that the 12V rail of PSU may flactuate to about +-5% of 12V, then the cooling power of my TEC will be:

min cooling power (Watts) = (12V / 1.05) x (15Amps x 0.75)
= 128.475W
max cooling power (Watts) = (12V x 1.05) x (15Amps x 0.75)
= 141.75W

If my calculations are correct, then I could say that the PSU will be sufficient enough. The cooling power of 120W - 140W is also sufficient enough to cool my AMD 2400+ processor.

Are my calculations correct???? :confused:
Will the PSU overload??? :confused:

You might want to go for a bigger TEC than that. People are using 172W TECs on video cards these days, not CPUs. Something like a 226W unit would be better.

Guys i know almost nothing about tecc cooling. Only the basics. So with my cpu(intel pentium 4 s478) what tec should i use? I want over 226w. Where can i find it?
Also which psu should i use in order to power that little monster...?

eBay, and as big as you can get. :)

oohh ok! thanx! now for psu...which one guys? I think i will go for a 300w tec...i think my watercool will handle the temps...

They say you should look for something (probably from a reputable manufacturer) that has 20A+ on the 12V line. That should be enough.

+20A @ 12V, that will probably be a 400 - 450W supply

But watch out, your 300W tec could use different voltages and current. My 240W TEC uses 15,6V 26A, but there are TEC's that use 26A @ 25V for exemple.
Just search what the max U and max I for u'r TEC is, and then search for a supply.

Just now i spoke to a friend and he said that he could give me for free a 400W psu from a case that he bought. The case is aopen. I dont know the amperes jet but, generally, i believe it shoyld be enough... :stick: :confused:

Also although a part of it is greek, what do think about that ferrotec in the middle. The only thing that concerns me is that its 40x40 and not 50x50...Also its imax is 15a...if i powered it with the psu mentioned above, i wouldn't get the best of it. Correct? I am confused ... :confused:

http://www.checkmate.gr/products.php?cid=12

Technical data for Ferrotec TE-9505/127/150B:
http://www.ferrotec.com/usa/thermoel.../products2.htm
Imax 15V, Vmax 17,5V
With that 400W supply u will not have the maximim 147W Qcmax, since u can have only 12V.

:( Ok then. What if i used redkens psu. It says that its 12Voutput is 13~15,6...then i would be ok right? Also, which is best, 40x40 or 50x50?

Never mind. I found my psu. I am going for it. it is this one click me This is all in greek so, i am transelating...it is capable of 40A, and i can manage the volts from 5-15. and it is weighting 2,1 kg...

Any increase in voltage is better, as long as u don't give it more voltage then Vmax.
40*40 or 50*50 does't make any difference I think. But check if u can fit 50*50 under your heatsink/waterblock. If the heatsink doesn't cover the intire TEC's hot side it would not be cooled good enough resulting in bad functioning of the TEC.
The only thing that counts is Qmax. The higher Qmax, the better the pelt will cool (if u can cool the hot side enough).

Ok thanx. I would buy a custom block but he cant make one right now. So i will go for a maze4.

Do you guys think an Aerocool 550W would be enough to power a TEC rated for 320W and 26A @ 15.3V? I would run it at 12V and the power supply's +12V rating is 25A (that should put the amperage draw from the TEC to around 20A, right?)

Thanks for any info. :)

I have a TEC over here rated also 15,4V 26A. It's the CP1-12726 from Thermal Enterprises. Mine has a Qmax of 243W, but maybe u got the same?
Last week I took an old 350W supply wich had 16A on 12V rail, and the TEC worked. With my water @ 10°C my pelt gave -18°C unloaded. Loaded this gives a big difference offcourse.
I still wonder why your Aerocool only has 25A @ 12V, my Antec 480W has even 26A @ 12V. Maybe I try again this weekend with the Antec 480W supply.
But if I were you, I would give it a shot, if the supply is only for the pelt, and not the intire pc. U can power-on the supply by connecting the green with a black wire on the ATX power connector.
Remember, to be more Xtreme u can always make your own supply squizing every little bit out of the pelt :)

The power supply was cheap at the time and it works for what I'm using it for. :) I'll probably need to upgrade my main system power supply eventually, so I thought I might be able to use my old Aerocool to power a pelt.

I'm going to hold off making my own supply until I see if the Aerocool will work or not.

Thanks, Wittekakker!

:confused: Have the OCZ 520w, want to get two 226 peltd for my Xeons. The power supply runs at 33a at 12v rail, which would not be enough to get aleast 80% of the pelts with everything else or would it... If not, what size switching supply should be used or additional psu

You could try getting something like this for those pelts:

Its very cheap and has a strong 12V rail which is what you need, but you would need one for each.

You need about 20A for a 226W at 12V, I'd spec 25A (continuous!) to be safe. You're probably looking at dual supplies for that, though you may be able to find a 50A model.
I wouldn't recommend an ATX PSU for large TECs.

You're likely to nuke that PSU pretty quick running such a large load on it. Fine for testing, but not a good solution for long term use.

So would it be safe to say that the cooler you keep the hot-side the more cooler ooorrr more efficient the cooled-side of the TEC. I understand about the watts but I hear so much about coolin the hot side, does that have anything to do with how the cooled-side proforms.
Some what new to the TEC design, boutght a 226w with 320 switcher in the mail but lery about adding to sys. until i understand more.

Yes the hot side temp matters. Generally cooling the hot side will cool the cold side by a similar amount. However TECs become less efficient as they get colder which can reduce the gains.

Wires weren't gettin hot with that 16A supply.
As I said, i tried out the 28A supply. With my water @ -7°C, I got a cold side temp of -43°C. Thats a delta t of 36°C, and wires heating a little bit. Without any heat load!

Stil have a question. If u cool one part of the hot side surface worse then other parts of the hot side, will that infect the working of the TEC?
Example: the hottest spot is 50°C and other spots are 30°C on hot side, will that make the same cold side everywhere? And if delta T was 50°C, will the cold side then be 0°C or -20°C?

Sorry to interupt....agian.... ?.

For two 24v 437w TEC at 32amps..can it be powered by a 12v 800w at 36amps.

Kinda muck up with this...please explian

Well, since u will be using only 12V, the current the TEC's need will be much lower then 32 ampére. IF they were linear, they would use 16A then, and since 16*2 = 32, u'r supply would be able to give enough power. But, watch out with some pc power supply's, there is some real junk out there.
And also: I'm not quit sure the TEC's would use 16A @ 12V. IF they were linear they would, but only IF.

Sorry my question might have been worded wrong...each TEC is 24v 437w at 32amps
The power supply is the Meanwell SCN-800w 12v at 66amps...so once again can they be powered with that psu.

Sorry still learning

Since you take a power supply with 12V, the TEC's will only get 12V. This is not going to destroy u'r supply or something, so don't be affraid, but it is just like that. So the TEC's get only 50% of there maximum voltage. If the TEC's work @ lower voltage, they will also drain less current. Let's say TEC's react linear, they would only ask 50% of the the maximum current -> 32/2=16A If they were linear, but I can't answer that question.
So if each TEC is only using 16A, u could almost use 4 TEC's on that supply.
But then again: why buying such a big TEC if u only use halve of it. Then u'r better with a smaller one i guess.

Ok now Im starting to understand how this work so the main concern is matching the volts so not to loose 50% of every thing else. But yet addin two TEC to say the Meanwell SCN-800 24v 33amps.. I will still be cutting the amps in half too 16amps so I need to make sure that the TEC will evan operate at such low amps than required. So I need to be looking for a power supply for one TEC*2 which i have not yet found a 24v with 66amps

?...with the amps, when adding two TECs the amps will be cut in half but not the volts
psu
http://www.computronics.com.au/meanwell/scn-800/
TEC
http://www.frozencpu.com/exp-04.html

Putting the TEC's on the meanwell SCN800 will destroy the supply. The TEC's will ask more current then the supply can give, so the supply will be working >100%.
Can u work more effective then 100%? Don't think so :) The supply will be able to hold it a few moments, but after a period it will die. I killled 2 supply's last week by doing this.
Normally u use the TEC's in parralell on your supply, wich means the voltage keeps the same for each TEC (24V), and the current we be sepperated for each TEC. If u give each TEC 24V, they will each need 30A. So conecting those in paralell, u will need a 24V 60A supply, atleast. The Meanwell SCN1k5 will do the job.

dammmm....wit everything was lookin good til I scrolled all the way down bout fell out my jar...my wife asked if i was okay :D. But it is a 220 which i don't think will work for me unless.......I use a voltage converter.

I know it's possible to hook up tec's this way as I've seen it mentioned around the web but does anyone know how this affects the power requirements?


I've got a ghetto tec that I robbed from a cooler/warmer. It has a little switching psu that gives 5.8a@12v according to the label. I don't know what the tec is rated at but lets pretend its 60 watts.

If I hook the positive of the first tec to the supply and then the negative to a second 60 watt tec then the negative of tec 2 to the negative supply lead what happens?

I know a 60watt tec is too weak to stic on much of anything. My question is more theoretical than practical as far as actual cpu cooling.

Anybody know? To make it work what volts/amps would I need in theory?

tia

Well, u could use them in series too.
Connecting in series, the current will be the same for the two TEC's, but the voltage wont. Were in parallell the current is devided into two for each component (if they are the same...), putting them in series the voltage will be devided into two.
So with 2 12V/6A TEC's, u will need a 12V 12A supply with TEC's in parallell, or a 24V 6A supply with TEC's in serie.
I would use parallell, because I think it's safer. U see, when one of the two TEC's has a little different resistance, it will get more voltage then the other:
U=R*I, so more R and I stays the same, U will be bigger.
That could be a problem if the difference in R is more bigger then u think it might be, and one of the TEC's will get more U then it's maximum voltage it may get.
So U > Umax of the TEC -> doing this much will kill the TEC.
With two TEC's that are the same u wont have much problem, but there is always a possibility it could happen. With TEC's in parallell, u can never have this. If u don't take a 24V supply with 2 12V TEC's in parallell that is :D
I'm not quit sure about this theorie, I'm no teacher in electronics, I'm just using some basic formules if learned once I was still @ school. But it makes sence to me.
And if u really were about to do use the TEC's, just use parallell, it had been done all around the world, so no worries for u then :)

hey guys, i gotta question with a bunch of ambiguity here. im finally gonan put a AMD heatsink on my vid card, but i ahve a pelt here from a while back. form what i rember its a 127 watt pelt form dangerden. yea i know this is a worthless number but i cant find out what kidn it was, or any signifcant measurements about this unit. a firend jsut gave me an old power supply an "extremo power super silent power supply 550w" wiht NO modle number on it at all. he bought this unit for 13 dollars aobut a year ago and it is the lightest supply i;ve ever picked up, so im kidna doubting it can really put out anywere near 550watts. the lines are 3.3=28A 5= 30a 12v= 11a.

now to the question. do any of you think that i can reap any kinda of benfit using acpu coller and pelt? or will i be creating more heat that dissapating, and do you think this powersupply will power anything worth a pile of rubble?

anything you guys can thinkg of/find, tis much appreciated. thnx again.

I was wondering if an OCZ powerstream (520w) with 33a on 12V would be sufficient for one 226W tec? This would be the only powersupply I would be using for the whole system. On it I have an overclocked opteron 165 (300x9 @ 1.65V) overclocked 7800GTX, 2 HD's, 1 optical drive, DFI expert mobo, swiftech 120 Rev3a watercooling, sb audigy 2.

you need a second powersupply to power the tec

Ok thanks!

ive looked at 50 different power supplies all i want is something that sits on my desk looks decent HAS A KNOB ON THE FRONT TO VARY THE VOLTAGE from 5v to 18v or what ever the correct max voltage should be for one of these devices. It will only power a SINGLE MCW5002-AT™ LIQUID COOLED THERMOELECTRIC ASSEMBLY that claims it draws the following specs: 226Watts 25A at 12V thermoelectric module. Oh and by the way i would like to not have to ebay my left nut just to pay for the damn thing. can someone point me to a specific make or makes and a few model numbers that will fit the bill.
Thanks a Ton

Just wondering what sort of wattage i want for a tec. my chip is clocked at
3.025GHZ (3700+ sandi) using a arctic cooler 64 PRO. at load it is appox 45 degrees. Could i use a SFF PSU on its own to power a tec im only after using a single tec on the loop.

I need to run two 80w pelts on a normal ATX PC power supply via molex. The pelts are all that will be on the power supply. I have two power supplys:

#1
DC +3.5V +5V +12V -5V -12V +5Vsb
Output 17A 13A 15A 0.3A 0.8A 2A

Enhance Electronics Co., LTD. Model No. ENP-220D 200W Power Supply

#2
AC Output Current +3.5V +5V +12V -5V -12V +5Vsb
10A/5A 26.0A 32.0A 13.0A 0.5A 0.8V 2.0A

Raidmax Model No. KY-520ATX 420W Power Supply

Can either of these power supplys handle two 80w pelts via molex? Also for my application of one of the pelts I actually want condensation to form on the cool side. How much condensation do you think would form?

Thanks

spingk I am still new to tecs but I think the #2 would work!!

would a 226 watt tec be able to power off a antec true power 550 watt spare psu i got its got 36A on the 12v rail plus maybe some fans and a pump

You need to mod it to provide higher capacity wires to the peltier, cant run it off a molex. And you need to apply load to the other rails.

i dont get what you mean about the higher capicty wires?

Gauge wise...

what would be the worst case scenrio if i didnt solder bigger guage wires on there?

Used a 240W tec on a Antec trueblue, I didn't got any problem using it with that PSU. Noob, not all PSU's have to be modded to use 12V only.

get a 226w tec and the meanwhile 320w psu :D

can you smell smoke?

I have a Swiftech MCW60-T (12-19V Tec) and i build a 14V power supply on my own (16A). Is there any power supply available on the market, which can operate 17V @14A?

he can use the tec on the powersupply as well but in time it will melt all the insulation and catch on fire! if you want to risk that then go for it but when you don't have a house take pics so you can say "this is what I did with a tec!!"

If I remember it right, Meanwhell has adjustable 24V power supply's. Though, they will cost you some money.

I'm looking to power probably two but I'd like to leave room for 3 TECS:

Currently its just 1 CPU (226) and 1 GFX (80), but in the future I might go x2 GFX.

First, how do I hook up the TEC modules? I read online -- someone said you should do it in series, but that means each one will only get 6V right? That seems wrong. So I guess in parallel? :confused:

Second, what capacity of a PSU do I need? I'm looking to build my own actually.

get the 600w meanwell and it has room on it for 3 tecs on it. IMO

wats that? i suppose you're referring to the SE-600-12?

yes or go with the 24v and take the Voltage down

Well I'm thinking I'd rather get a good PSU with a high current rating, so I'll have room for expansion.

I'm going to be using up to 3 TECs, 1 for CPU, up to 2 for GFX (only 1 right now). I'm going to switch out my Antec TrueBlue 480W psu and replace it with this. Would this psu power my system AND power TEC's?

SilverStone ST85F (850W / 900W peak, +12V1 thru V4, 18A a piece

No... You will melt the wiring. Get the meanwell to run your tecs

What? You can't plug TECs into a molex? Why would some TECs you can buy (for ripoffs) off like FrozenCPU have molexes? What about like 80W ones? At 12V they would only consume about I dunno 70-80W, I think. Would a molex not handle that?

You are going to need alot more than 80w tecs try more like 226 or 320

on a tec it draws 35A and your 12/5 volt rails on a pc psu will never run that many amps! you MUST use a psu that can handle the load!

Yea but read the specs on that PSU. It has a total current rating of 72A! Isn't that sufficient?

ERrr.. where'd my post go did it get deleted?

Well, here it is again. Basically I was saying that the PSU I picked has a total current max of 72A. I'm also undervolting the TECs, since their Imax ratings are based on >12V. In that case, would the PSU be sufficient?

Nope. You CANNOT use TEC"s on a computer PSU especially with a lot of current.
