can i use two pc psu's to get 24v?
Yesterday i had a great thought for getting my macintosh powerbook 190 to power up. If i used two 12v sources in parallel i could get 24v (i think thats what it is, i mean where one power supplies negative is connected to the others positive and the neg of one and the pos of the other are used to create a combined voltage).
So i tried it with one pc power supply but then i realized the 12v's are all connected to the same circuit so hooking it up like that would just short it out.
I tried with two wall adapters, and on my voltmeter, it gave me around 30v with no load. the only problem is, that it doesn't supply 2 amps worth of power. but the 12v line on a pc psu supplies at least 10 amps, so if i used two pc power supplies (to prevent any shorting out) and hooked them up like described, could i get the 24v @ at least 2 amps that i need for this?
Thanks in advance,
