can i join ATX PSU in series/parallel?

[witchhunter]

I need 15V 25A PSU for my 220W TEC. Secondly I have space for only 2 joined PSU, and the only 12V 13A PSUs available are ATX ones. I know that with ATs there's no problem, but what about ATX? Can they be joined parallerly (spel?) ?

I really can't afford spending 120$ + 30$ shipment to get a nice 5.25 fitting unit... any other suggestions for making/building such a PSU?

i tried that a year ago (followed all directions) and my rails went way down below what they were supposed to be.

if you want something like that..buy a redundant PS

If your just powering a TEC, why don't you just buy a Micro ATX PSU. They're fairly small, and you you have a lot more options as to where you can place it.

Well sure, but find me a Micro-ATX PSU that has 24A on 12V

Hi,

here is an article BUT:

Do this at your own risk!!!!!
And I am not talking about frying you system -
THIS STUFF CAN KILL YOU!!!!!!!!!
Be sure you know what you are doing!!!
There is stuff in the PSU that needs to be discharged!!!!

Got that article already, but you see, as much as i rememer there is no word about using or not using ATX supplies... that's the reason for that thread...

There is a 1-2 ohm resistor mentioned in that article, what if I wanted to bridge the 5V lines, do I still need a resistor across 12v?
