Lucky me
 

Today I dropped by a local electronics shop and found a second-hand power supply that gives 24V, adjustable by 10-20%, and the beauty is that it gives 64 amps at 24V! There are actually 2 modules in it with one being able to give 24V 32A, so if one spoils, I can use the other. However, I need to buy both because it won't work without the rest of the equipment. And guess the price? Only US$80+ for this beast! I'm gonna test run my rig and if it works without problems, then I'm gonna buy the power supply to give my pelts a higher voltage than 18V. Should give me better temps since I'm quite sure my hotside is handled well.

What make was that and where can I get one?

I bought it. Its says Powerone DC power supplies. I really have no idea where to find another one like it though. The sad thing is that temps only improved 1-2C at best from the 18V to a range from 20-24V.

Check out this page, thats the brand of the power supply I'm using, they sell a lot more powerful power supplies. http://www.power-one.com/products/acdcintro.html
You can even pick the parts you want for a custom power supply.
I have the 1500 watt model that is 24V 64A

Nice aquisition. :D

ohh man that seriously rocks.

how many pelts are you going to hang off it?

Yeah can't beat the price I got it at. Right now only powering 2 172 watt peltiers. I was thinking if I wanted to chill the water then I'd need around 4 more 172 watt peltiers to get water 10C or below. That would be about the max it can handle, 6 Drift 0.8s. But then I was thinking I'd be better off with a compressor chilling the water. Or maybe I'd get better temps just using the 6 peltiers to chill the water. Water peltier-chilling on top of peltier-cooled CPU is almost as hard to implement as peltier stacking, just that you can't directly stack 4 peltiers on 2 peltiers on a CPU, or can you? It would be cool to see that.

you might be able to put 4x 172w ontop of 2x 172w, that would be a very interesting project

If you can find those even higher powered pelts then 2 on 2 would be better, with the 2 on the cpu underpowered.

uhh fut, care to explain that? I've lost you there
