Ok I'm thinking about getting a 80w, 40mm X 40mm peltier. I guess it comes with the two wires just hanging off of it. My question is how do i connect this to my power supply, and should i connect it to a second power supply just for it. Any cheap power supplies you guys could recommend that would run it?

Peltier Question
- Thread starter ec_hern
- Start date
Let me be the first to say that
#1 Hooking up a peltier to a cheap power supply isn't going to cut it
#2 There's alot more to using a peltier than just hooking it up, you still have to contend with possible condensation, and you also have to cool the peltier itself. It doesn't automagically make the heat disappear, it's just very efficient at transfering heat from the cold side to the hot side. You still have to remove the heat from the hot side, or you aren't doing anything.

right, other side is going to be water cooled.
Not sure how great of a power supply im gonna need if the only thing on it will be one peltier.
And how does the peltier conect to the power supply itself? Most peltiers I see need 12V. Do i solder in the peltier wires to the square ATX 12V connector, and just power up the power?
Or do i use two of the normal molex connectors that are used on hard drives and stuff and use 2 out of the 4 plugs. I'm not sure exactly where the wires go but I'm sure i could find it online.
and i already know what im going to do about condensation.

Here's Mean Well Power Supply. The right PSU for TECS. Can you post your WC rig components.
It's a pricey PSU.
It's a pricey PSU.oh man i hope i dont need that mean well, does everyone that has a peltier using one of those?
also Mav... not to sound like a noob but what does that mean, are those the sockets where i plug the peltier wires into? and if that is correct is that using the molex or atx 12V connector?

what do you guys think about this one....

is 12vdc the same as 12 volts?

skimp and watch your system die a painful, painful overheated death =)
You need to get a second AT or ATX power supply for that pelt. Whatever wattage it consumes, take that and add 100W for good measure. Just because it's an 80w pelt, doesn't mean that is it's power usage. That is more likely the heat transfer capacity.
You're spending the money for the pelt + water cooling. Unless you want all that to be in vain, invest in the power supply. If ATX, you'll need to jumper the ATX connector to allow you to turn the power on.
And those voltages I listed were for molex connectors. Take the two wires from your pelt and connect a new molex, or splice/solder/heatshrink it to molex connector. If you don't mind it being permanently connected, you could just cut off a molex from the PSU and hardwire it, but that's ghetto.

not looking to skimp, trying to figure out what i need.......
these guys talk about using a 330w enermax to power a 80w peltier,
http://www.cluboverclocker.com/reviews/power/enermax/eg451p-ve/
thats with the system running off of it also, and the only thing that will be on the one im lookig to buy will be the peltier.
and I really want to know how the hell the peltier is physically connected to the power supply, like what connector do i plug that red and black wire into.
arg help! heh

THanks Mav!!
got a switch that im gonna use on the ATX so i can turn it on and off easily.
Guess ill got with a solid 350w PS, antec enermax, something good. Maybe 420 for good measure...
ok, so im assuming the red pelt wire goes into where the red molex wire is, and the black will go where the yallow one is?

NO NO NO!!!!
The red wire from the pelt is 12v, which should connect to the *yellow* 12v from the PSU. The black ground wire can go to either black ground wire from the PSU.
If you connect it the way you stated, it would run at 7v. BTW, are you using this for a CPU or GPU?

Why would you want a switch on it? Peltiers that aren't turned on are very good insulators, so I don't really see why you would want it off at any time.
And what kind of power supply do you currently have? I don't know why these guys are telling you that you need a 300-400 watt power supply solely for an 80W peltier... Try to find some specs on the peltier, like Vmax (max voltage) and Imax (max current draw). Multiply those 2 together and that's how much power (wattage) the peltier can safely use. Add about 10-20% for a safety measure, and that's how much power you should allot for the peltier.
Generally an 80w is safe for quite a few powersupplies. Just check the amperage. If it's a 12V, and you have enough amperage on the 12 line, then you're golden. Remember, your system will probably take between 10-17amps on the 12volt. So add in the usual 7amp of an 80w pelt, and you get between 17-24. So you'd want a PSU with 20-27a on the 12v rail if you run it off the same powersupply.
The times you really need one of those meanwells is when you're dealing with a bigger pelt than an 80w. The ones that go higher than 80w tend to use more volts than 12v, and also require a lot of amps. So they aren't practical, as you can't (safely for a long period of time) overvolt the 12v rail.
And yes, a good 350w PSU would probably run your computer + the pelt. Just remember to check those rail volts before buying! Enermax and Antec are the good ones.
I recommend that when you first try a TEC, setup Motherboard Monitor with an auto-shutdown temp that is lower than meltdown. That way it gives it a few brief seconds to power that baby off.
AND DEFINATELY, run the water pump / radiator fans seperate from the PC. That way if the system does shutdown from heat (while you are away?), and you are running it off a second powersupply (like you plan), the water can still cool the pelt.
