80Watt peltier on a 400Watt PSU???

[One_Hertz]

I am wondering if i can stick an 80 watt peltier on my x800XTPE. I have some kind of 400 Watt PSU. Running on it i have a 12 volt pump, Intel p4 cpu running at 3.6ghz, a hard drive, videocard, mobo, cdrom, floppy, and ram. Will my psu fail if I plugged in an 80 watt peltier into it?

with all that i would say that your psu would start to crash. that is alot of strin on your psu without the peltier

[echow87]

you can always get a meanwell psu online that handles an 80w pelt, goes for $25 or so.

Yup, I would look into the meanwell....more then likely that your psu wouldn't be able to handle it.

K thancks a lot. What is that meanwell psu you guys are talking about?

Check ebay for meanwell power supplies.

K i got a free one from my hardware teacher. The psu is 250 watt rated 22 amps. Is that good enough to run 2 80 watt peltier. If it is not then can i use it somehow else?

Sorry i am a noob at this. :(

What voltage are the pelts.

What are Imax and Vmax?

[One_Hertz]

Imax is 8 amps and Vmax is 15.2 volts for the video card and for the processor the Imax is 24A and the Vmax is 15.2 volts as well. I am guessing I'll need buy a good psujust for the peltiers, right?. Also is it too much to run 2 peltiers on one radiator? I haven't decided which radiator to get yet cause i dont know which one is best, same for the pump.

[Holst]

Your 22 amp PSU should handle 16 amps no problem.
But are you sure it will work upto 15volts?

You will need a bigish rad to dissipate the extra 243watts from the pelts, (thats max wattage, it may be less)

But are you sure it will work upto 15volts?


Lol i not sure about anything right now, pelts are confusing... So very confused... My 400 watt psu is rated 35 amps but still only 12 volts. I don't think i ever saw any psu being able to handle more than 12 :confused:

I am guessing I will have to buy the meanwell one for another 100 bucks cause I really dont wanna buy used stuff, had enough bad experiences with used computer parts already.

K screw the cpu 226Watt peltier it ends up being simply too expensive with a new psu and all, besides my liquid temos will probably suffer a lot. What if I plug in my pump into the :banana::banana::banana::banana:ty psu and put a single 80 watt peltier into my 400 Watt, now without the pump?

[Nimrod0031]

If you are going to be running the rest of your system from this thing then I would not recommend running the pelt from it also. What all will the psu be powering?

I will be running a 226w pelt and 80w pelt soon so I can let you know how much heat you will have to deal with. I am going to try 2x 120.2 rads to dissipate it.
